Hi, I'm a kindergarten teacher, and my class is trying to make plaster hand printsI'm having a hard time finding a mold to useI was trying to use a 8'' round cake pan, because a) it's a good size for their hands, b) the depth is good, and c) round is a good shape for themHowever, the plaster won't come outDoes anyone have any suggestions for a different type of mold or how to get the plaster out more easily?
