I've read about people who find a quilt with a label in a quilt store, hunt down the family, and return it to them. I dread that happening to me some day. I don't want the quilt back and I don't want to know that's where it was found.
My first thought about this Project Linus quilt is maybe the child died, or was adopted, and the family decided to pass the quilt on to someone else because of the memories attached to it.
