I've been thinking quite a bit about form lately. As a result, I've been throwing mugs with different shapes and sizes, both the see how they function AND to see how they sell. My latest collection is a group of very wide cappuccino/latte mugs, after having read about and watched videos of "latte art". You can see examples of it here:

I also threw and handbuilt a "Revisited" Seder Plate made of small, deep cups rather than a plate with shallow bowls. Certainly an interesting form, and interesting to make -- thinking of the actual ergonomics of it and the technique of getting it all together.

Next step? A craft fair in Austin to see how all this experimentation works commercially!
