Although I have a non-clay related full time career, I have been a Architectural Ceramist for many years. I backed into ceramics from a wood carving hobby when I needed some tile for a rehad that I was doing. I couldn't find what I wanted, so I carved my own originals, made molds and produced the tile myself. The rest is history.
Over the years, I have added to my collection and now have hundreds of molds. These kinds of projects kind of take on a life of their own!
I also throw from time to time and teach that subject matter at the Paseo School for the performing and Visual Arts here in KC as a visiting artist.(a secondary school)
