I made a king size crumb quilt and I still have bins of scraps. I throw away anything smaller than 1" square and anything less than 2" square goes into my crumb bin. I have my scraps sorted by colors and I cut them into strips or squares according to the pattern I am making. I have even used 1" strips to crochet rugs that last forever. I made a shower curtain out of my scraps once. You cut your fabric into 2.5" strips and cut the long strips into 7" or less. Put them into a laundry basket and reach in and grab a strip and start joining them. The only rule is no 2 strips that match are sewn together. Roll these strips until you have a ball about the size of a beach ball. Decide how wide you want your project and cut off that length from the ball of scraps. Sew rows together and then line. I sewed along the lines between the rows and then put binding on it. I made button holes at the top for the shower hooks and I have been using it for over 30 years. Naturally you don't use a batting. It was a lot of fun and easy to make.
