When I'm done with a project and have scraps leftover, I put them into the tote named for the closest size they could be cut down to. If its a fairly good sized piece of fabric but too small to fold back up, I put them into one of the 2 smaller totes I have just for "large pieces. So when I go to work on a new project I know I can look in there for decent sized pieces 1st. Just the other day I went to the "large pieces" 1st to cut a bunch of 5.5" squares. Working on Missouri Star's cathedral window method and found my 5" squares didn't work so went there for all the reds and then to the "fat quarter" bin. Found enough to do the job. The 5" squares went back into the "5" bin" for another project.
