Like so many people who work "small", I have a lot of trouble with my back, neck, and shoulders. I've noticed that my posture is just terrible when I sit in the regular office chair I have at the torch. I try to remember to sit up straight, but the dumb chair really encourages slumping. So I ordered a yoga ball chair. It arrived yesterday, and it's cool! Sleek and beautiful, and the big red rubber ball is like a giant toy. I'm sitting on it now, nice and straight. And rather than slumping, it encourages bouncing and stretching. It's even supposed to work those pesky core muscles I'm so good at neglecting. I don't know if this will be good for beadmaking, but I'm sure going to give it a try. Guess I'll have to cover it with a beach towel, so flying glass doesn't pop it! Want one of your own? I got mine from Amazon. Here's a link, and a photo. No that isn't me on the chair... I'm much older and fluffier!
