As I sew I cut scraps into "Lumber" pieces...4 x 4, 1 x 8, 2 x 4, etc. I do strip quilting and crazy quilting and use pieces as small as 1" square. I also keep a tub full. Took one to a class yesterday and shared with ladies who had no scraps. We were doing strip quilting. It was fun to share. There is always someone who needs lots of scraps. I think an exhcnage or knowing someone to send them to would be great.
