Wait a minute, she charged you $50 more than she quoted and she didn't finish the quilt? I certainly wouldn't have paid her until the quilt was done, and then I wouldn't have paid her the extra $50. She gave you a quote, and that's only what you should have to pay, unless you had requested additional quilting or something. She should have finished the quilting and stood by her quote. I wish I had a solution to your problem though. Hopefully, someone on board will have an answer for you.
