I am real new to quilting but my stash seems to be growing. I organize my stash on cardboard and then sort by amount and color. All the 2 yards one place, etc. Then when I know a project needs so much I can go to that area first. Fat quarters are organized in shoe boxes by general color or theme. If I have a complete project all set up, I keep it all together so I can find the thing when I am ready. I use plastic food storage boxes from Dollar store to organize projects and then label the outside. I use to use baskets but sometimes they fall over and everything falls out. Plastic boxes have lids and the clear box makes it easy to see inside.
