I'm trying to expand my techniques and have recently become fascinated with stenciling and using molded fondant/gumpaste on my cakes. So I have a question for all of you who are exprienced in this. Can I use ANY stencils and molds that I'd like or do they have to be made out of food grade plastic? For instance, if I see a row of butterfly stencils at the hardware store, can I use those? Also, if I use RI and stencil the pattern onto wax paper and let dry, how long do I need to let it dry before lifting it off and putting it onto the cake?

Thanx for the help!
