I love to quilt for my own pleasure, not to stress myself out trying to be perfect. I would ask her if all she see's in my quilting is things I had done wrong or if there are anything positive about my quilting. Then I would say, one needs to hear positive as well as having one's mistakes pointed out. It will discourage some to the point of quitting something they had wanted to do. If she does not understand that you need to find someone with better teaching skills.
