Hi, I'm trying to get butterflies on a cake (giving the illusion of them flying around)..I want them paper thin, was going to print on frosting sheets but then they wont' be double sided...any suggestions?

Welcome to CC! you can use gelatin for your butterflies, or royal icing, chocolate...or you can paint them on both sides of your paper.

I did mine out of gumpaste. They aren't as thin as you would like (I wanted them thicker to put the wire in), but you could easily make them thinner. In hindsight, I could have made them thinner since the bodies covered where the wire was anyway.

Or I have seen some done out of gelatin. I don't know how to do those.

I've never done it myself, but I recall seeing some that were printed on rice paper. They were super thin and I think the colours could be seen on the underside.

I use rice paper and then color them on both sides.

Here's a link to a tutorial on realistic butterflies. I've been wanting to give it a try, but haven't had the chance!
