Lion Mold

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.
