I keep scraps/trimmings from each project in a small plastic zip bag so they are already color coordinated. Strips go into a storage bin for future LC's. Tiny scraps get used for leaders and enders because my Bernina is picky and tends to snarl thread on the first few stitches. There is quite a bit of information on this Board regarding leaders and enders for you new quilters. It took me awhile to find out about them, but once I did it sure saved me a lot of grief!
