I"m sorry, never used gumpaste before, will my gumpaste swans get soft if I keep it in the fridge overnight? My cake needs to be refrigerated, and I want to have the decorations on as I have to leave at 5 am tomorrow with it....

Unless I tested it in advance I would not try it.

You are risking it. Just depends on how much you like to gamble and then scramble if it messes up.

well said, point taken. I took them off. just have to get up earlier....no biggie. thank you.
