Beautiful story and quilt...lots of great names have been suggested, I don't think I can add something new :(
Your story reminded me of when I was a child. My parents (now in their late 80's) had an accordian like that in the back of the closet. We kids would pull it out now and then and pretend to play...What a racket!! But it was fun. I had not thought of those times in a long time.
Thanks
