You sound like me. While I am working on a quilt I often think about the one I 'think' I'm making it for. Then someone will see it and want it for theirselves or for a different charity.
I really am glad you showed this. You made a beautiful quilt. I love Irish Chains and have thought more than once to make one with stars for QOV. I don't have this pattern but I don't think it would be hard to put a star in the empty block. Your idea for your class reunion is great. Wish I had been in your class- lol
