Make the shape of your gummy out of a product called, Amazing Mold Putty. Once you have crafted what the shape of your gummy candy will be – to make a mold of it, you can press it into a block of a product called, Sculpey. Follow directions on how to harden the Sculpey mold. Once that is done – you can pour the gummy candy into that mold & voila! You have a custom made gummy candy.
