I'm sooooooo jealous. There are a million ways to use 2-1/2" squares. The problem is deciding which to do! I love Mondo bags, and I've made 2 - perfect for carrying things to classes - or to carry your loot at Quilt Shows. Scrappy 9 Patches sewn as beginners and enders would be my 2nd choice. The sky's the limit!
Please show us pictures of what you do.
