I love making my own silicone molds but the molding putty can get expensive! Well, not any more. Check out my cornstarch and silicone molds that cure in about 20 minutes! These molds are super easy to make (also a bit messy) and you can make tons of them for very little money. In my crafty lab, I found that air dry clay, Sculpey and 2-part plastics work best in these molds. If you're not familiar with 2-part plastics, they are wonderful and cure in about 10 minutes. I'll put a link to where you can get some below. Have fun, go forth and make molds!
The stop watch mold is one of my favorites!
Add a little paint to give them some color!
Try the putty on a small statue or doll face!
