So I'm learning a new way to make foam latex puppets for stop motion and I'm freakishly excited about it! Before, I was creating puppets by layering sheets of foam over the armature and then cutting away using tiny craft scissors to create the shape of the puppet. It was a very slow, tedious process and getting a smooth surface was difficult. But with this other method, you create a sculpt of your puppet, create a mold from that, and then you can foam your armature using the mold.
