re: Gum paste/ fondant figures

Thank you for your replies. I have been running the air con continuously….but when I turn I off the fondant immediately starts to sweat and turn soft. And I’m now making my figures entirely out of gumpaste, but they still soften. Recently did Jake in 3 pieces – head, torso and legs. The spaghetti would not hold the head and torso together. He kept listing sideways. Izzy was seated so I had more luck with her. But any free standing figure is difficult to work with.
Also what brand of fondant is best to work with here?
