Well, this is what i would do. The second quilt is very whitewashed, but you also couldnt have known what she wanted. You shouldnt re-charge her, because someone not liking it is a risk you take, but i would say this, maybe to avoid this in the future, maybe take a layout photo before sewing, and have person see it first, just an idea. Anyways, this is what i would do, the blue rows on the second one are what i would change. It wont be hard to do at all, and the quilt will still be nice. Try and replace those blue squares with something floral, like the pink floral in the first quilt, or that pretty pink strip was nice too. All you have to do is this, cut your squares out, press the edges under, and then hand applique the squares onto the quilt, and nobody will be able to tell, the quilt will be very nice. So sorry this happened to you, but no, i wouldnt charge her, consider it a lesson learned, and take photos along the way next time.
