My stash is, for the most part, by color. But also divide them out by fabrics from one line stored in a bin drawer labeled "sets." Another drawer for "Children." Another labeled, "Themes," which holds animal prints, beach, food, etc..." Another bin drawer holds aunt grace type fabric. Another hold flannel. But the bulk is sorted by color on not-tall-enough bookcase with glass doors. I also have a basket that holds charms.
