Amybaby, it's special and I would use it all the time! Your father took time to think it through, to create what he thought you might like and how it would make it easier for you while quilting. I think he did a wonderful job! When my father was alive he did the same thing. We would talk about things and he would start to create. He worked alot in the garage and garden. It was probably to keep peace with mom!! But his creations were so loved and treasured that I miss them. I have several around my house that he made and they will always be treasures to me.
Take the time to fill it and send him a picture so he can see what a wonderful job he did!
