I want to do a cake for my dad with FBT of us scuba diving but to make it look 'underwater' I wanted to do a thin layer of piping gel over the top (piped, not spread with a spatula). Will that blur the image or cause color bleeding? Anyone ever try it?

Thats a good question to know! Im curious also...I dont see why it would hurt it...if your careful...hopefully Dawn will know...she is the one who did the tutorial on transfers.

I'm curious too. Do you have a link for "Dawn." ?
