I'm planning a wine bottle cake--two (gum paste) bottles, actually--and am trying to figure out what to use for the label, which I'll be drawing myself freehand. I had planned to use wafer paper, but am worried about it warping after I apply it to the gum paste with piping gel. But I worry about working with an icing sheet--will it dry out too quickly while I'm doing the artwork (it'll probably take at least 15-20 minutes), and then crack? How long do icing sheets stay pliable? Any advice on the pros and cons of both would be greatly appreciated!

Ugh, that's a tough question. I had my wine label printed on an icing sheet and it worked great. Wafer paper is so susceptible to moisture I can't imagine it not rippling on you some just while you paint it. Maybe email the Icing Images folks. I bet they can tell you how long they can be out. Sorry I wasn't much help but hopefully someone else can help.
