The worst thing you can do is to keep your anger and resentment inside. It eats you alive. Perhaps one day when you're having a nice conversation with her you could politely tell her how expensive fabric is and how expensive it is to have someone else quilt a quilt. Tell her very politely. Hopefully, she will get the message. Also, there's the old one of write her a letter and tell her how angry you are about the quilt and never mail the letter. It helps to relieve some of the anger. You might also try forgiving her for not taking care of the quilt the way you wanted her to take care of it. Lastly, no more quilts for her. Even if she asks you to make one for her, the answer should be no. I remember how you took care of the last one I made for you.
