You could use them on a puff/Biscuit quilt by using them as the top square, and making the bottom square 5.5 inches. I will post a picture of the one I made, but recently I saw one that had buttons sewed to the center of each puff. Next one so going to have buttons too! This puff quilt was a request by DH for a really warm quilt. It hangs down to the dust ruffle on my Queen bed, is backed with a heavy flannel sheet, and weighs 7lbs! Never tell me you are cold, I will fix it! Good luck with whatever pattern you chose.
