I use plastic shoe boxes for various colors, too, and find they stack well on shelves. I also have a basket of "strings," and shoe boxes of 2" and 2.5" squares. I find the 2" squares very helpful when I need to shop for a particular color. I make a lot of scrap quilts and use them regularly. I wouldn't cut everything into 2.5" strips because I often make my borders 3-4" wide. Multiple yards get hung on hangers in a closet. Good luck with your organization project!
