I agree with many things said... Between my own issues and seeing my mother struggle to keep sewing, I have done a few things to help. Raising my chair is definitely helpful. I use an office chair that has that capability and also has a lumbar. I also added "The Gypsy Sit Upon" My Mom wasn't able to use it, but it does help me. Raising the cutting table has helped as well. I have an island in my kitchen where I do my major cutting now. I raise my ironing board for smaller stuff. Mom also uses an "airplane" neck pillow (bought at the airport) with beads in it which she wears when she is sewing. She also bought a shoulder/neck/back "blanket that she puts in the microwave to heat it up. (She got it thru "Harriet Carter" I think.) I think the idea of not sewing for hours on end without getting up and stretching is a great suggestion that we do as well. Some of it is trial and error finding what works for you, but definitely find a solution as stopping entirely should not be an option.
