An excellent idea. As our population ages, I suspect more and more of us will find ourselves in the position you or her family are in. A quilt may help. A while ago I ran into to son of a very dear mentor. We talked for quite a while. He thanked me for the insights into his mother's life. She was disabled shortly after his birth, so he never saw the hugely dynamic, outgoing and socially important person I knew. Your gift may help the family focus on the earlier, very positive parts of her life.
