Lets look on the positive side here.
The quilt was still on his bed which means he must really appreciate it, holes and all. It was probably and accident, and we all know accidents do happen from time to time. I would definitely mend it for him so that it remains on his bed so that each time he looks at it he will think of you. Isn't that what making quilts is all about? I am an avid quilt maker and I totally appreciate the time and expense involved with making quilts but lets not lose sight of the important things in life.
