I am going to attempt to make a shoe out of gumpaste, I am going to make all the pieces individually and then when they harden put them together, I was just wondering if you can use glue to put them togrther or will it break down the gum paste?
make sugar glue out of gum paste. Just add vanilla to soft gum paste until it's a liquid glue consistency. Pipe it into the areas you want stuck together and let it dry. Another option is royal icing - does the same.
