The rest of us seem to think you gave the quilt to your son & Daughter-in-law as a gift. That makes it their quilt now, to use as they see fit. You need to let go. Life will go on. Just because you give a gift does not mean you get to dictate what the recipient does with it. If you think you are unhappy now about the quilt, you will be devastated when they stop talking to you if you persue the issue about the quilt with them. Just say thank you and let go.
