I,too, think your quilt is lovely and a few loose threads and maybe some uneven stitches are really minor issues. I believe you said this is a memory quilt. This quilt shop has now added a very bad and sad memory for your customer. She will always remember their comments. That is so unfortunate because it will never be what she had intended it to be. I guess the same can be said for you. Try not to let this discourage you. There was no way you could have foreseen a situation like this. Keep on quilting!
