I don't get neck and shoulder pain anymore. Used to when I quilted in the traditional way, sitting down. Now I place my sewing machine on my cutting table and quilt standing up. I cannot even describe the difference this has made for me! I will never quilt sitting down again!
In order to have a flat surface to work on, my wonderful dh made a styrofoam surround for my machine when it is on the cutting table. What I really like is that it is lightweight enough for me to move around, plus it stores easily against the wall when I don't need it. Got the directions from Youtube:

If you haven't tried quilting standing up, I urge you to try it!
