I have only used satin ice gumpaste so far, and it has worked perfectly. I roll my gumpaste out paper thin, then I grease my mat, put the gumpaste on it and roll it out more, until it doesnt stretch or move anymore on the mat, then I let it set out for an hour and a half, then just set what I want to cut, and cut. I cut out 75 2-inch letter E's, and 75 1 1/2 inch swirls. It didnt mess up at all. HTH!!! GL!
