These faces are done with polymer clay. A few years ago my supportive and creative wife suggested I try making faces with this sort of clay during a time when my back was "out" and I couldn't make pottery on the wheel. Working out the detail was fun as I learned by trial and error. I started making ornaments for our Christmas tree and we still use some of them.
I enjoyed making batches of these little guys and was truly flattered when a co-worker hung one of these guys from her review mirror in her car. I used a good bit of blue and orange as a nod to the college football team while we lived in Boise Idaho.
