I'll show you step by step on how NOT to make your own mod podge. Enjoy!
1. Get your supplies
2. Fill jar half with water, half with glue.
3. Shake the hell out of it.
So here's what went wrong. I think the proportions of half and half are wrong. The podge definitely needs more glue in it. My jar came out looking exactly like milk. Pretty sure if I put it in the fridge, my mom would put it in her cereal. It was just a big pile of watered down glue. The podge was disgusting and not at all what I was hoping for. I'll probably dump some out and add more glue, hopefully I can save it. If you are going to try this DIY use 1/4 of water and 3/4 glue. I believe those measurements will work a lot better and won't end up giving you a jar of watery goo.
If you've tried this DIY and it worked out, let me know!! Or if you have any tips on fixing where I went wrong, leave them in the comments below!
