CD, I was interested in reading about your thoughts on chairs with wheels for treadling. I too thought they would not work as I figured that I would keep pushing myself away from the machine. However, I use two feet for treadling so maybe a wheelie chair would not work for that method? Not sure so guess I should try an office chair to see how I do. Right now I just have an old wooden chair from my grandparents house that I use just because I have it and don't need it anywhere else. However, the wood does not match either of my treadles but I suppose that does not matter in the long run since it appears that's what people did back when treadles were the only machines around ..... meaning that they used whatever chair was available. Interesting topic .... oh and thanks for the photos. Still liking the piano stool idea even though it does not have a back.
