My sorting is a little odd, or at least compared to what some people do. All of my fabrics go in a big rubbermaid tub because I don't have a sewing room :( But first they all go into piles, florals, solids, holiday, large prints and small prints. Then they all get organized by color after that. And any piece that's smaller than a piece of paper goes in my scrap box. Anything that's part of a project gets put in a gift bag which is kept on my bookshelf so that I can just grab the bag and don't have to worry about accidentally using that material. Good luck!
