I wish there were classes for adults as well. I know a few years ago there used to be classes near the art store next to what used to be Grand Market. Most likely if you go to the art store there they can tell you if such classes are available. If you find some let me know please. Thanks!
I went to that art store but they didn't know about any pottery classes. They told me to explore the Paris Circle area and ask small shops there. Will let you know if I find something out useful.
@vwbug you can visit Gilgamesh Art Cafe, they have pottery, stained glass, glass painting and campfire events. This is their website: gilgameshartcafe.com
