Remember where I was trying to figure out how one of the cake decorators got elaborate patterns like a flag on their fondant, then wrapped it around the cake (on another thread)... WELL I finally have the answer. I didn't figure this out, I got it from someone else. They roll out fondant and spray it using a stencil and airbrush! But, I haven't cracked how they do it with chocolate plastic. Still hoping to figure that out, but the method has to be the same (air brush and stencil). I'd guess their using the oil based chocolate coloring pastes and thinning them down... Wouldn't that work?
