How do you work with rice paper- does it disolve into the cake icing-buttercream or fondant.
Can you copy it on a copy machine, what about eating the paper with the picture/printing on it.?

I'd love to know also! Where can I purchase it?

It's properly called wafer paper. you must use edible inks in a dedicated printer. It does NOT melt into the icing.

If you want it to melt into the icing, you'll need to use an icing sheet.

I use wafer paper for butterflies and flowers.
