Here is my lion mold (or mould as it's spelled in other parts of the world). I would love to make lots of tribal masks but it is a slow process. One of the ways to speed up that process is to be able to vacuum form my molds. I'm looking into making a vacuum form table. There are several plans for that on the internet that involve a home oven and a shopvac. For now, polymer clay is the way to go.
