O. K., this has happened to me. I put a piece in backwards, didn't catch it. Had it quilted, finished, the whole deal. Then my "friend" (lol, she really is my friend), said La, La, you made a mistake! Anyway, I called my LAQ told her the problem, she said she would re-quilt it for me. I took the quilting out, fixed the error, took the quilt back to her, she fixed the quilting. Then I put the binding back on. The only good thing is, the error was down at the bottom in the corner. Thank the good Lord for small favors. If it had been up in the middle, I would have said I did it on purpose!
