I sort by color with large pieces in bins. I also sort by fat quarters in flat bins and those by color. Since I am an avid 30's lover I have one flat bin just for those then in color sequence. When I have small pieces of fabric I add them to the fat quarter bins or if they are really small they go in a separate place until I get a wild hair and decide what to do with them...usually a doll quilt or small wall hanging. I also have a separate bin for Christmas, another for baby and other holidays, plaids and one for checked gingham. That is how it is now but who knows, I might decide to redo! I simply love my stash!!
