I just came across this video, and I just love the bit towards the end, when he says that on the first day of wheel throwing class, he always has his students throw it 'til they break it, as this is an important step in throwing - and growing. Yep, did that, though not really on purpose. And my teacher could save it by cutting off the top, as it was the wall that broke because it got too thin. So I guess I can only grow now (and hopefully my bowls too, when I finally get the hang of pulling the wall).
He's got a great series of videos for beginners. Of course, it's much better to go to a class, do it yourself, and have a teacher helping you. But watching and observing others is helpful too. But of course every potter has their own way, and my teacher is doing some things differently than he does. But the basics are the same. And I still just find it simply magical when they pull walls!
