Definitely good therapy and definitely music! I vary what I am listening to. If I am piecing and moving from my machine to the ironing board then to my cutting board I usually have something a bit peppy on. You will find my singing and dancing from one place to another! But if I am machine quilting I need something a little more mellow so I can concentrate a little more. I'm kind of glad my sewing room is in the basement so most people can't see or hear me!!!
