We have worked one the wheel about 5 days now. I've been successful in bringing the clay up and down . I have also managed, just last class, to open the clay without pulling it out too far. I used a sponge to help me get the walls taller along with putting my hand on the inside to keep it from collapsing on itself. I actually enjoy working on the wheel except for the clean-up which takes a little while especially with several people using the sinks at the same time.
