Wow! She did beautiful work! I had an experience similar to yours where a longarm quilter had my quilt for a year - she had a problem which held her up from the first deadline, and then it just went on and on. I had pretty much given up on her, but I finally got it back and her quilting was absolutely stunning. Of course, I paid $300 for it (no discount offered for the long delay). I probably won't use her any more because she seems to have a hard time respecting deadlines, although she is the best quilter I've ever had. My experience with LA quilters is that most of the time, they miss their deadlines. Artistic temperament maybe?
Anyway, I would probably pay your quilter the $200 you had originally talked about. Not a bad price for two gorgeous quilts. I love both the patterns and you did a beautiful job on them.
