It is interesting to read about your quilting experience over the years. You have much more experience than I do. I've only been quilting for about a year and a half. I have never done any hand work and have no desire to. All my work is done on my machine. I've read stories about the Amish getting together to quilt and it sounds like you have had a similar experience. I love your "perfect mistakes". Now I have a name for mine!
