re: Modelling paste goes quite dry and cracks

Hello Shaz, and welcome. I, too, find gum paste / modeling paste too dry for making figures. Either it drys too fast or I am too slow and I suspect the later to be the case. You could use fondant with a small amount of Tylose powder added. It will take a lot longer to dry, but it will also give you more working time. Personally, I always use modeling chocolate, but it takes some practice.
