Way to go with more organizing!
For fabric size pieces that may be a FQ or 1/2 yard, I ruler fold using a 5 inch ruler. Then fold up again so they make 5 inch bundles. These pieces are stored in a plastic refrigerator bin approx 6 inches wide x 16 inches deep. I stand them upright so it's easy to see the color and sort. These bins also hold all of my charm packs and keep them organized. The bins fits into a drawer unit for storage. The fabric pieces would also fit into one of the double scrapbook bins.
Yardage above that size are ruler folder with a 6 1/2 inch ruler and stored with like colors or patterns.
