What a heartbreak. How did the LAQ determine pricing-by inch and pattern? If you told her 124x124 and she did not believe you but took the job, then that's her error and she should be working with you to complete the quilt, rather than giving it back. I may be wrong, but I believe once she had the quilt on her frame, she would have been able to tell size, then if oversized, at that time should have declined BEFORE starting. I would go back to her, voice your unhappiness, the difficulty you now face, and inquire why she accepted the job, started on the job, but is stopping unfinished, and is there no possibility to quilt the other two side panels. It's business negotiations on both sides.
