I have a book, RX for Quilters. The author is a physician and a quilter. She talks about taking care of your body, and your hands, when quilting. She talks about how to care for the callus you develop on your fingers, how to pre-treat your fingers before you begin quilting to prevent soreness, etc. She talks about all of the areas affected when quilting, carpel tunnel, eye changes, back pain, etc. If you can find it, might be worth the investment. I dug my copy out with all the discussion of sore fingers, but the rest is interesing as well. It was put out by C&T Publishing, copyright 2000.
