Painting Plates or, an exercise in combating perfectionism

Guess what?  Last weekend I took Jack to paint some pottery.  We went to a place that actually glazes and fires the pottery so you can eat off it, it can even go into the microwave.  Jack was in the most horrendous mood ever, I'd let him have screen time half the morning and he was pissed that I was dragging him out of the house and into the world.  When we got there, he picked a plate and started drawing on it with a pencil, and was uber-frustrated when he learned he could not erase anything.  I forced him to carry on amid wails and lamenting (much to the chagrin of the lady working there, and the other customers).  He did comply however, painting in all the shapes he'd planned out, and I helped a bit with the black outlining (just tracing his original graphite, which burns off in the kiln).  In the end, we had a pretty fun time, depsite having to help him calm down repeatedly about mistakes he perceived in his work.  The plates turned out pretty well I think, here is a photo:

I'm not sure he learned his lesson in the end, these came out way more perfect than I anticipated!
