As a new quilter, I realized early on how quickly scraps pile up so I just started to cut them down to precut sizes after each quilt. Then, before I started the next quilt, I would sew 10" blocks of different block patterns (or the same pattern depending on what I had in mind) As the 10" blocks pile up, I select enough from the collection and make a scrap quilt. I just keep adding to the blocks until I have enough for a quilt. Any extra scrap pieces I put in zip locks by color and store in plastic container for appliqué projects. Most of the time I make a quick charity quilt after each quilt I make. Seems to keep scraps at a minimum. If one color becomes too unruly, then I make a quilt with that fabric. I recently had a run on green and made this quilt. I went from 3 gallon size zip locks to 1/2 bag. Piano key borders are great for getting rid of scraps.
