Hi Stephen:
I work making leather masks and I teach also the technique of molding leather, if you are near Stockholm, Sweden I could show you. Otherwise there is a very good description of the technique in Thurston James book "The Prop Builders Mask-making Handbook". There you will find many other methods and materials for making masks. You can find this book in the book section here at Masmakers Web.
Enjoy
Augusto.
