Hi, New to the cake decorating scene and was wondering how to cut out different shapes without a mold?

AHi. You could print a shape, cut it out and the place it on top of your rolled out fondant/gum paste/modeling chocolate (whichever you prefer) and use an exactly knife or some other sharp utensil and cut around it. You can also use cookie cutters.

Thank u so much !!! I will try that

ARoll out your fondant thin, place in freezer for about 5 minutes, then cut with exacto. Freezing the fondant helps when cutting out intricate shapes, it keeps the fondant from stretching.
