Isn't it the point to create more quilts in whatever manner? Here in Japan, most quilters are just learning to use sewing machines for certain quilting chores, but my great-grandmother used a sewing machine extensively. However, she still had a frame she dropped down from the living room ceiling and had friends over to quilt by hand. They did it for the companionship. And they surely got more quilts finished by working together.
If you begin to have problems with your neck, back, and hands, should you give up hand quilting? The point is you shouldn't have to stop creating just because the method changes.
