When I am piecing or cutting, the first time my mind wanders off (as it tends to do), I make an error! However, when I'm hand-stitching binding, my mind can go anywhere it likes and I make no mistakes. It's very relaxing. Ditto the seam ripping job I'm doing now. I am almost finished removing a wide border (one I thought would be right for the quilt, but is definitely not) and a narrow one (same huge quilt); I was NOT looking forward to this task, but I can really 'zone out' while I remove 1000's of stitches.
