I agree with Deedum, get back 50% of the cost. She should have called you and let you know there is a problem with the backing. A lady I know had a lab robe quilted, got it home didn't like the quilting and she took the whole thing apart and then took it to another quilter to be done over. The second quilter did a great job, I saw both jobs, first and second. She didn't go back to the first quilter but told everybody under the sun how unhappy she was with the first job. Things can get nasty.
