I accidentally left a wad of fondant out about 10 days ago. It's so humid here that when I found it yestarday, it was as moist as when I took it out of the bucket. So, of course, I use pure gumpaste, which actually won't get totally dry here, either. When the design lends itself to pastillage (it's not very scuptable, but it can be cut), I use that. It's the only thing I've found that will actually harden in this climate.
