Night Sky Activities for Preschool: Galaxy Slime

We are really digging this night sky theme! My kiddos and their classmates are really into sensory exploration right now, and the starry night sky lends itself to so many amazing sensory activities. Today we delved into the world of slime and gak for the first time, and I’m SO glad we did- the kids played with this for hours, and Daddy even joined in the fun! I can’t wait to take this to school with us to see how the kids’ classmates react- I’m betting they’ll love it just as much as we do!

How to Make Galaxy Slime

DIY Galaxy Slime by Twodaloo

Since we’ve been studying the night sky at our cooperative preschool, the twins have been talking about it quite a bit at home. They especially love talking about stars, so I showed them some artist’s renderings of the Milky Way galaxy that I found in one of my reference books. As we were admiring the swirls of color, a lightbulb went on in my head, and the idea for Galaxy Slime was born!

Making the slime was pretty easy after I figured out the nuances. Yes, there are nuances to slime making- I’m as surprised as you are 😉  ANYWAY, to make our cosmic slime we built upon the tried and true recipe of equal parts Sta-Flo Liquid Starch and Elmer’s Clear School Glue. I wanted our slime to consist of several galaxy colors so I could swirl them into a big spiral for the invitation, so I made smaller batches of black, turquoise, violet, and white/silver using the following proportions (I used the recipe below for each different color):

So here’s the skinny on slime-making…you gotta take it slow. The first time I tried it, I just dumped all the ingredients into a bowl at once and started mixing. After 20 minutes and really sore wrists, it was pretty obvious it wasn’t coming together, so it went into the trash. So I tried again, but this time I followed a different progression. You’ll want to put your glue into a bowl first. Then add your coloring (I used liquid watercolors but I’ve heard that food coloring works, too) and glitter and mix well. THEN you can start adding your starch, but just add it in small increments at a time, stirring well to mix after each one to incorporate your starch fully. After the first couple of additions you’ll need to use your hands to knead the starch in, just like you are making bread dough. Another thing- I know the common wisdom is equal parts starch and glue, but I never needed the entire amount of starch. When I did use the entire 3/4 cup of starch, the dough become more like a gak and wasn’t as stretchy as I wanted. So, just add a little at a time and do a “stretch test” after each increment is kneaded in. Once your slime is the consistency you prefer, STOP!

If you are a regular reader of Twodaloo, you know I love presenting sensory play in fun ways. I decided to spiral our colors together on top of our mirrored tray from Ikea to suggest a sparkly galaxy. I thought it looked pretty inviting, and sure enough, the twins wasted no time jumping right in. My son in particular enjoyed this material- something almost as stretchy and active as he is!

He was completely enthralled with the texture. He wanted to feel it with his hands, his arms, his feet…everything.

Both of the twins were very fascinated with the stretching. And this slime has plenty of streeeeetch!

It’s funny- typically with sensory materials the kids love to add loose parts and/or “guys” (little figures) to engage in some pretend play, but they weren’t interested when it came to the slime. They were just content with exploring it on a purely sensorial level.

 Even after all the colors were mixed together, the slime remained beautifully colored and inviting.

I mean, have you ever SEEN a more gorgeous slime bubble? Seriously. Also, “gorgeous slime bubble” is not a phrase I would ever have predicted would be in my lexicon. Just sayin’.

Don’t worry- more on those slime bubbles coming tomorrow.  While Will was busy cheesing for photos, Syd was up to her elbows in her own little project, and I can’t wait to share it with you! (Click HERE to read how we tweaked this recipe to make GIANT REUSABLE BUBBLES!!)

Instead of reinventing the wheel, here are some of my most popular posts on the benefits of sensory play- be sure to check them out!

The Science of Slime

Although we used this activity as sensory play rather than a science lesson, making slime is actually a pretty amazing demonstration of how polymers work. If you are looking for more hands-on STEM activities for preschool- and elementary-school-aged kids, I wholeheartedly recommend The Curious Kid’s Science Book by Asia Citro (author of the Fun At Home With Kids blog). I love this book because, unlike most other science books I have come across, Asia focuses on the inquiry process and helping children design and test their own experiments, which is great for problem solving, higher level thinking, and most importantly keeping that wonderful curiosity and love of learning alive.

  1. Love it!!!

  2. I love it too! Now I just have to see if I can find out what liquid starch is 😉

    • Stephanie says:

      Hmm, I wonder if there is an Aussie alternative? From what I understand you have to use the specific brands I linked to or it doesn’t work, probably because Sta-Flo actually contains a bit of Borax. Will have to dig into that one!

      • Have you had any luck with Aussie alternatives Stephanie? Would love to try this. It looks great. Ohh, with the kids…but maybe by myself too.. lol

      • John Southerland says:

        First, i can’t tell you how awesome it was to find this. I had done this very project (minus the glitter) when i was in grade school but lost the recipe and could never find it again (this was pre-internet). So awesome to find this so my new nephew can have fun with this like i did. Second, i would think any liquid starch will work for an aussie substitute, you just need to add a teaspoon or two of borax. Not sure about adding it before or after the starch. Third, you don’t state which colors you use to get the ultramarine look.

        • Stephanie says:

          Hi John! Sorry, it’s in there I promise! I made batches of black, turquoise, violet, and silver/white (omitted color and just used lots of silver glitter for that one) and swirled them together. Hope that helps!

  3. This is super cool!

  4. Natalie says:

    Is the liquid starch safer than borax?

    • Stephanie says:

      Hi Natalie! There is lots of debate about the safety of Borax…if you do your research it’s really a mild irritant that is only harmful if ingested in large quantities (just like salt would be). A lot of people confuse Borax with boric acid, resulting in lots of confusion and misinformation. However, I know there are lots of people who avoid play recipes made with with Borax, which is why this was originally posted as “Borax Free.” HOWEVER, I just did some more research and found out that Sta-Flo does contain a small amount of sodium tetraborate (borax) so I am changing the title. Sta-Flo is classified as non-hazardous but can cause stomach upset/vomiting if ingested in large quantities, so no matter what you use to make slime (Sta-Flo or pure Borax), it’s definitely not for eating and children should be supervised during play. If your kids are still tasting sensory mediums, save this until they are older. Hope that helps!

      • What about the glitter? Pretty sure we don’t want kiddos to ingest glitter. Common sense applies to everything about this recipe. If your children put everything into the mouth, keep it away from them. If you don’t want slime on your carpet and upholstery, keep it outside or play on hard surfaces that are cleaned easily. :)

  5. I really, really love that you used purple. i think it’s the most gorgeous slime I’ve ever seen.

    • Stephanie says:

      Thanks so much Allison! That’s a huge compliment coming from you!! 😉

  6. Can’t get enough of this gorgeous slime!!

  7. Thanks!!! My kids loved this activity!!

  8. jade baker says:

    Does this keep in an air tight container? Any ideas on how long? I would love to make a big batch and share with some friends.

    • Stephanie says:

      Hi Jade! It does keep in an air-tight container, you may have to knead it a bit to return it to the desired consistency, but so far ours has kept beautifully. I have heard from others who love this basic recipe that it can last for months if you keep it stored properly, so you should be fine sharing with friends!

  9. I’ve just a workshop on Sensory Play for adults to do with kids from 0-6. Your site has been great. Thanks.

    • Stephanie says:

      Oh wonderful, Sally! I’m so glad you can use some of our ideas and information! Thanks so much for stopping by!

  10. This is so cooool and pretty!! Love the glittery slime!

  11. Sarah M. says:

    Is it messy? Obviously, anything that you give to a preschooler could turn into a mess, but is it sticky or hard to get off/out of things like carpet, fabric, clothing, hair, pet fur, etc.? I wouldn’t leave my son alone while he played with it, but it seems disaster can strike even if you turn your back for a second!

    • I have made gak with my son since kindergarten (almost 9 year old now) and he loves it (still) BUT Sarah, you are correct in your thinking about the mess.

      No matter how many times I say “at the table, in the kitchen, NOT on the carpet or chairs or….” – you know what happens. So far that which of traditional gak has ended up on the carpet or a chair is now a permanent reminder of why I haven’t made any more.

      I’m assuming that with the glue as an ingredient this recipe will be the same as well. I’d love to know what Stephani has to say on this.

    • Stephanie says:

      Let’s see, so far we have gotten our slime on the walls, our kitchen chairs (wooden), our Pergo floors, our tiled floors, our skin and hair (I TRY to minimize the hair exposure, but I have two three-year-olds!), our clothing, and on the dog. It has washed clean with warm soapy water from all hard surfaces in our dining room and from our skin and hair as well (although I’ve never let it totally dry in their hair). Since it does contain school glue it will harden when it dries out, so expect it to perform similarly. We haven’t gotten it on our carpet or upholstered furniture but I wouldn’t recommend it (just like I wouldn’t recommend squirting Elmer’s glue on your carpet or chairs, LOL) but I have heard from others that this type of slime will come out of carpet with vigorous scrubbing (again, I’d just try to avoid that). It has not stained our skin or clothing- I assume because the color is encapsulated in the mixture. So it’s up to you how much mess you are willing to tolerate- you could always make it an outdoor activity if you are leery! Hope this helps!

  12. I love all your ideas but live in Australia and some of the products you use I can’t find is there any alternatives to lily sops and sta flow liquid gel
    Thanks for your great ideas.

    Regards june

    • Stephanie says:

      Hi June! I don’t know if there are any alternatives that are exactly the same in Australia- I just use what is readily available to me. Basically you will have to experiment with liquid starch and school glue until you find a mixture that works for you, or you can find an alternative recipe that includes ingredients that are available in your region. I know you can make slime with Borax and glue or Psyllium fiber supplements as well- do some Googling and see what works for you!

  13. I never made Slime, can be stored for use again? Thanks.

    • Stephanie says:

      Yes! Store it in an airtight container or plastic baggie and it should last weeks or even months.

  14. Joan Ball says:

    Can you tell me what the equivalents would be in the UK?

  15. I have wanted to make these slime recipes before but as I am in the uk I haven’t been able to get hold of borax so I was excited to see this didn’t need any. However it appears I will also not be able to find sta-flo liquid starch, is there a specific ingredient in the starch I need to make the slime slimey and I can search for products with that ingredient?

  16. Mel Baggaley says:

    Would live to make this fir our recrption children but need to find a uk equivalent, if anyone can help I would be really grateful x

  17. Im in the UK and I know PVA is just the same as Elmer’s bit not So sure about the liquid starch, I did track down borax but it was really expensive.
    What would you use liquid starch for normally? That might help us figure it out.

    • Sta-Flo liquid starch is used when ironing clothes. Our military uses it regularly to keep our pretty creases. We put it in a misting bottle with water, spray and iron.

  18. Does anyone know what the English equivalent of Sta-flo is please? I’d love to make this slime with my girls, it looks awesome!

    • Gena Kraemer says:

      If you look up liquid starch in the UK it lists Dylon Easy Starch. I also found it listed in another recipe that called for Sta-Flo as a substitute.

  19. Gena Kraemer says:

    If you look up liquid starch in the UK it lists Dylon Easy Starch. I also found it listed in another recipe that called for Sta-Flo as a substitute.

    Does the glitter stay in the slime or do you find it slowly works its way out onto the table & the kids hands?

    • Stephanie says:

      Thanks for the information about Dylon! I am not much help on the UK equivalents. We have been playing with this slime for weeks now and no glitter has worked its way back out. Hope that helps!

  20. Stacy Taylor says:

    Discount School supply has liquid watercolor with glitter in it!

    • Stephanie says:

      Sure does! Although to get it as glittery as ours, you may want to add even more glitter on top of what’s in the DSS watercolors.

  21. I was wondering, what colours of watercolour paint did you use to get the wonderful “galaxy”? It looks like navy blue and purple, but I am not quite sure. Thank you.

  22. Thank you for this wonderful recipe!!!! I live n Brazil and there is no Sta-Flo but I’ll be experimenting with what I find. It will be great to surprise my daughters, who think mommy is quite boring

  23. Velma Green says:

    I absolutely LOVE this!!!! I’m a former preschool teacher & I was nicknamed the “Flubber/Playdough Queen” because I made either one weekly!! I used borax whenever making Flubber (slime)…I don’t recall ever using liquid starch & I didn’t know that it would have the same end result with it!! Thank you for posting this & giving me a fresh new idea!!!!

    • Stephanie says:

      Flubber/Playdough Queen is a fantastic title! I LOVE playdough and am a new slime/flubber convert as well…I’ll share your throne with you 😉

  24. Hello! This looks so fun. My sons will love it! I don’t have any of the ingredients, though and the liquid water colors are so expensive! Does anyone know a cheaper alternative? Thanks!

    • Stephanie says:

      You can use food coloring instead of liquid watercolors, although food coloring does stain more (liquid watercolors are generally washable). Hope that helps! If you plan on using liquid watercolors regularly, they are actually quite affordable because you can use them for anything you would typically use food coloring for in crafting (not for eating though). And you can dilute them with water and stretch your bottles foreeeeeever!

  25. Your recipe says clear Elmers glue. Does the white work as well? I know it would make a difference in the color, but does it work for the consistency?

    • Stephanie says:

      I haven’t tried it but I have seen plenty of others use white glue with good results!

  26. I’m lost. Where do I see how to make this cool looking stuff?

  27. Stephanie
    This idea has myself and kids enthralled. We are going to make a batch this weekend. Would you be alright if my 9 yr old uses this for a project at school? We will disclose full credit to you and your blog.

    • Stephanie says:

      Of course! As long as you cite your source, you are free to use anything you find here…that’s what we’re sharing for! Good luck on the project!

  28. This is such a neat thing. My kids and I are enthralled by this and look forward to making our first batch.

  29. cup Sta-Flo Liquid Starch, is this the equivalent to Borax, if so do you use the same amount.
    Kind regards

  30. Christina W says:

    Ok I might have missed this but is it a 1 time use or how do you store it? Thank You.

    • Stephanie says:

      Hi Christina! If you store it in an airtight container or Ziplock baggie it will last for weeks or months!

  31. Deana Wolstenholme says:

    I couldn’t find the liquid starch so I made my own. One cup of water + 3 tablespoons of water and 2 teaspoons of Cornstarch. Mix the cornstarch with the three tablespoons of water and when smooth add to the cup of water and place in a pot and cook until thickened. Allow to cool and viola! Liquid starch Borax free. Works with this recipe.

    • Stephanie says:

      Awww, man! I just tried it in the recipe and it didn’t work! Did you actually try it in the recipe?

  32. Lenore Stout says:

    Ads came up for all the products on Amazon, an amazing site where you can get anything. I would imagine that although the ingredients are cheap, the shipping to UK will be astronomical!!! Once you buy a lot of stuff from them you qualify for “Prime” shipping but at you distance that may not apply. Try it and see! Good luck! Can’t wait to try it!

    • Stephanie says:

      There is Amazon UK as well, but I don’t think Sta-Flo is listed there. Boo.

  33. This is super cool! I can’t wait to try this with my son. He’ll think I’m the coolest mom around!

  34. ImadirtyHooe says:

    I’m a wonderin is dat shit hurtin my lil lb’s and lg’s? my lb tasted dat borax sheit and loved it . he can’t even get enough once. I go out shoppin all happy like and he asks me for dat borax doe and I’m like oh hell no boi ain’t no bawdy got time fu dat shit

  35. Hey Stephanie, this is such a great idea and fun. I wanted to know which specific colors you got? I was thinking of getting individual bottles instead of the set, and I really liked the colors you chose.

    • Stephanie says:

      Let’s see, I used Turquoise, Violet, and Black for our slime. I left the silver uncolored and just added a ton of fine silver glitter. Hope that helps!

  36. Thinking about using this for kids to play with at a party. Can you give me any idea of how much it makes, or what number of children might be able to share a batch?

    • Stephanie says:

      Hi Debbie! The slime you see in the photographs actually consists of several batches- each individual batch makes about 5-6 oz of slime (the amount of glue in the bottle plus the volume from the added starch). So I’d plan on making several batches- each batch is probably enough for 2-3 kids to have a good handful to play with. Hope that helps!

  37. How much slime will one bottle make?

    Also, what alternatives can replace StayFlo. Our local Walmart is out of stock.

    • Stephanie says:

      See my reply to Debbie above for the amounts, and as for a replacement for StaFlo, you can try another brand of liquid starch, but I can’t vouch for any of them personally because I have not tried any others. And just FYI, online my Walmart says that StaFlo is out of stock, but lo-and-behold they have it on the shelves, so if you haven’t checked in person you may want to give it a go!

  38. Karen Poole says:

    My daughter in law showed me your link! I’m very excited to find this, my husband takes care of our two youngest grandchildren and I’m always looking for new activities to do with them! Since they were just babies (as I did with my kids) I have done crafts and activities with them and ones that include sensory stuff and any kind of learning is great! I wish you had been around when my kids were young, my oldest is disabled with speech and language disabilities and organic brain damage (of unknown ore). So as my kids grew up I tried to do this type of activity that would increAse the senses and speech and language abilities! He had a really great special education teacher early on that gave me lots of tips on working with him with sensory learning and why it was so important for a kid with his disabilities! But it is also important for the other kids too! Keep up the good work!

  39. I am in NZ and can’t get liquid starch (unless I buy it online, for $8 with $64 shipping…!) So I decided to experiment. I made some homemade liquid starch and then gradually added it to white school glue, colouring and glitter. It was lovely and smooth but all runny!
    I then tired adding dry cornflour, so sieved some in a little at a time stirring it in, and eventually it became sort of like slime! It is stretchy, but very sticky! I only had white school glue, and didn’t add any borax to my starch, so I might try again doing that and using the Elmers Clear School Glue which I’ve found in Warehouse Stationary. Thanks for the recipe! :)

  40. Borax is typically remembered as being a laundry additive think “20 mules Borax*. The reason why this is added is because it actually works as a great preservative. When you have these starches and liquid mixed together it becomes a field for bacteria to grow in. Borax is actually very commonly used in lotions as well. This will help prevent your slime from going bad with something that is relatively safe.

  41. this is the coolest thing that i have ever seen

  42. In one of your photo, do you put your cat in it???

  43. Do you find this to be messy/sticky when you make it? I made a couple of batches tonight, and they were a bit wet and sticky (getting stuck to our hands), and I wasn’t sure if I added too much starch, or should have used more? I used about a half cup. Think I should try something different?

    • Stephanie says:

      Hi Amber! If you are finding it to be sticky, add more starch. Keep kneading it in until it reaches the desired consistency. The more starch you add, the less sticky and more rubbery it becomes!

  44. ShileyBart says:

    I’m really sorry to burst your bubble, and this really is an awesome project for kids. But, it is physically impossible to take a picture of the Milky Way Galaxy. We can’t take a picture of something that we are inside of, unless we travel just outside the arms of our galaxy, which we have yet to do. Someone took a photo of another galaxy slapped “Milky Way” on it and threw it into a book. I’m not trying to bring anyone down here, I just hate seeing people being lied to, especially children.

    • Stephanie says:

      Hi Shiley,

      I’m sorry I wasn’t more specific in my post, but it didn’t occur to me that anyone would think I was lying to children! You are correct, we haven’t been able to take a complete picture of the Milky Way Galaxy for obvious reasons, but we ARE able to photograph small portions of it from within, and there are many beautiful artist’s renderings available that show us what our galaxy *might* look like when viewed from the outside based on our knowledge of the structure and appearance of other galaxies that are thought to be similar to ours that we have been able to observe and photograph. The photos that I was referencing in my post were actually a combination of partial photos and renderings. Thanks for your comment- I’ll change the wording of my post so that I’m not spreading any more falsehoods to the masses 😉 Have a great day!

      • Did anyone else feel the sweet burn that Stephanie put out there! (High five) Anyway, when you add the coloring did you make three separate batches and then flow them together? Thanks for the laugh and the help!

  45. Hi
    Is this like silly putty? We have found silly putty impossible to remove from clothing. That’s the biggie for us- will it wash out of clothes? Thanks!!

  46. Marissa H says:

    How long does it stay formed? Will it last for multiple days if kept in a tupper?

  47. This is a lot of fun. Its crazy but a group of my friends and I are getting together to make some of this. Mind you were are a bunch of 18-20 year old but still love this kind of stuff. I have spent the last two week trying to get everything set. after looking in 6 different stores 4 of which were art store I was unable to find Liquid Watercolor. So I found out how to make my own. I have that all set and so I set out to by the glue, another 6 stores later I cant find any clear glue or even normal white glue. Feeling almost defeated I was that my local Walmart had coloured glitter glue. I have made a batch using the glitter glue and that worked fairly well. I have run into the problem though that even adding a tbsp of sta-flo at a time the slime either was too stick to mess with or too hard to be more than silly putty. Any suggestions?

    • Stephanie says:

      Oooh a grownup slime party sounds fun!! Honestly, it’s probably the glue. What brand are you using?

      • Yes. Glue brand matters, we just tried Dollar store glitter glue just became running mess. Great for other project… throw on some paper mache.
        Used Elmers clear worked great! It’s a must.

        If stored in glass jar how long will it last? Can I make it the day before party? Thank You. Great recipe!

  48. Okay, I want to play with this, and I’m an adult. It looks fascinating. Time to go hunting ingredients

  49. Hey are using WordPress for your site platform? I’m new to the blog world but I’m trying to get started
    and create my own. Do you need any coding knowledge to make your own blog?
    Any help would be greatly appreciated!

  50. Im from the uk. But want to make this in summer holidays. Any ideas what sta flo over here might be?
    We are also collecting tube/ bottle etc to make the water station I saw few week back yay. Keep it up keeps me and my three busy abd messy :)

    • I know I’m replying over a month later but for anyone from the UK me and a friend just made gak using PVA and Tesco own brand non bio gel. We tried Aldi (per an earlier post) but it didn’t work. I think it needs to be the gel because it’s a higher concentration. I used food colouring, which gave a great result but the colour just gets on to everything so we’re back to white but with glitter in. If adding glitter or colouring, make sure you mix into PVA first then add non/bio gel (we didn’t test bio but guessing it will work as well as non bio).

  51. Melissa says:

    Hi. Was wondering if it makes a difference on white glue vs clear glue? Maybe the colors might not be as bright but anything else? Also- liquid water colors seem expensive – is there an alternative? Would regular food coloring work? Thanks!

    • We used white glue and was fine. Food colouring also fine but I worried about it staining things so we went back to white.

  52. I made the slime a few weeks ago and my son loved it. I used about 1/2 c of starch and the consistency seemed great. After storing it in an airtight container, however, the slime is now too “runny” and sticky to play with. Could I add more starch now to fix it? Or should I just start over and use more to begin with? Thanks for the great recipe!

  53. just made this and it turned out perfectly! so much fun

  54. Any answers for my July 21st question? I am also wondering, like some others have asked, about using white glue instead of clear. Thanks for the help and tips!

  55. This looks like so much fun for the kiddos, but I just wanted to put it out there that you need to be careful of the watercolors you purchase because some contain pigments that can be toxic, especially for children. I would be less worried about the borax, and more wary of the paints used. Thank you for all the wonderful ideas on your site!

    • Hi Megan,

      This is true of actual artist’s watercolors (the ones that come in little tubes, etc.), but the liquid watercolors we use are non-toxic and intended for use with children. Thanks for your comment!

  56. I just LOVE this idea! Just one question though: What was your process of adding the colours? did you add in the black first, then incorporate the others? I reeeeaaallly want to try this, but i don’t want to mess up on any scale :$

  57. Hi,I was wondering if I can use borax instead of liquid starch?

  58. Can we use borax instead of liquid starch and food coloring instead of water colors

  59. I don’t know if I didn’t use enough starch or what, but this was a bit of a fail for me. I made some for my 2 year old niece and 3 year old daughter to play with. I was trying to have it be stretchy and was nervous I would over starch it, so maybe that was my mistake? At any rate, it was SO sticky. The girls were excited at first and then got progressively more and more freaked out as their hands got more and more covered in slime. I tried to wipe/scrape off as much as I could and them go to washing, but ended up having to throw them in the bathtub to make it less torturous. Even during the “kneading” process of making it, I felt like I couldn’t get it off my own hands effectively and a lot was wasted. After the time I spent shopping for ingredients, then making it and in clean up, the rate of return of only about 10 min of happy play did not seem worth it. On the upside, I used washable liquid watercolors, took their clothes right off of them and into the machine, and it all washed out, so that was a big relief!

  60. I messed up the first time I made gak too…threw it all together at once into a ziplock bag. Didn’t think it was going to work, but after a day I squashed it more and it eventually turned to gak…but yeah, go slow and then you can use it same day.

  61. Your slime is so gorgeous! And I love the slime bubbles in the next post! So fun. I am doing a slime roundup post on my blog tomorrow and will be including your incredible galaxy slime. :)

  62. Just make some pink slime today. We used Linit Sharch instead and it worked. Thank you for sharing this.

  63. ive just tried mking this with pva glue and liquid starch….. but its just like im watering down the glue rather than stiffening it up. do you need to leave it for a while?

  64. Stephanie says:

    What type of starch did you use? I’ve heard that it can be iffy if you don’t use Sta-Flo specifically.

  65. Can u use white glue
