I know the feeling. A quilt I made my MIL is used to control the air drafts over the AC. I just took it back, and nothing else was said about it. Some people just don't appreciate manual work. It hurts more that it was your father, and nothing is going to make you feel better right now, but you put it aside later and go on. Don't let this change how much you enjoy quilting. You like it and that is all that matters. I think your quilt is just beautiful. You should see some of my early work...maybe not.
