You have a lot more sentimentality about the quilt than he does. He doesn't see how totally "cute" the whole idea is to show his son something he made when he was younger. He wants it fixed so it looks really decent. I would agree with the thought that if you want to keep it that badly, make another quilt for the baby and keep this one. Otherwise, do as he asks, as much as it may hurt, which is to fix it.
