I would rip it out. I don't know if I would say something to her or not. Depends on your relationship with her. If she feels she was really doing you and favor then she will feel you don't appreciate the effort and there will be hurt feelings. I would just not say anything. If she is starting out and going to be doing this for more and more people, you could be helping her in her craft by letting her know about the problems. If your quilt was made poorly (I'm sure that's not the case) but if it was, the machine quilter should be telling her clients this so there's no surprises. She needs to learn this as well. It would be as much fun for her to tell someone their quilt isn't well made as it is for you to tell someone their machine quilting isn't well done. I would add having chocolate along with the wine.
