Yesterday I was putting the finishing touches on a very large pot, maybe three feet tall, and accidentally stepped on my wheel's pedal. The pot spun at maximum rate and the center ballooned out way past the point of saving it. I worked two days on that damn pot and it's history. Then, probably coincidentally, my wheel just stopped working. All I did was step on the pedal, which I've done over and over for more than two years. But when stuff begins to happen it seems to happen all at once. Finally, while placing another large pot I'd glazed on a low shelf for firing I hit my head hard against the shelf above.
Still, a bad day at the studio beats a good day in many places!
