I haven't read the entire thread, but these would be perfect for a Mondo Bag. I can't remember whose design it is, but I LOVE the bag. It calls for 280 2-1/2 inch squares, so it would be GREAT to have them precut. I used batiks in mine, and I cut them from a jelly roll. I made mine in a Sue Hausmann class. Everyone used different fabrics, and they all looked terrific. It's a BIG bag - big enough to take a large quilt to Guild for show-and-tell.
