Its not quite done yet, but I plan on breaking down the whole process. Ill give you a spoiler, though.
Dissolve a little bit of dextrin in your water you use to wet your mixture. Its the same stuff that they used to put on the back of stamps that you had to lick, and also is used to bind loose powders together for fireworks!
Its realllly easy to make, too. Just bake some corn starch in the oven at 400F for about 2 hours, stirring it every so often so it doesn't burn. Once its the color of a manilla folder or a taaad darker, its ready. You can either add it to your water before you dampen your mix, or you can add a small amount to you dry mix. Adding it to the dry mix wont work as well if you are using lots of oils.
