I can't believe this was one of the first items I made out of polymer clay! I made it for my uncle and it creeps me the heck out. It's life-size on the large side.
Polymer clay is an awesome medium to experiment with because it is pretty inexpensive compared to a lot of art materials, so there's not much risk in messing up. I started out with only a few blocks of clay and one clay tool that had a curved end and a knife end. I'm planning on putting my first clay sculpting tutorial on here tonight to tomorrow.
