I guess I'd call myself a fabric collector so I have hundreds of fat quarters. I store all the batiks by color in photo boxes in my fabric closet. My holiday, and "themed" (kitchen, kids, loons, sports) fqs are folded to 3x5" in a large Rubbermaid under bed storage box on a shelf in the closet. The rest of them are ironed, sorted by color palette, and stored flat in a stack on top of a dresser used for storage in the closet. I have some coordinated bundles that haven't been opened so they will stay together as a set until they have been used for a project and then the balance will either go with my scraps or into the ironed stack if they haven't been cut. This system works for me and allows me to easily find a specific print or color when I want it. When I work, my mind is as clear or as cluttered as the room I am in. My sewing room is rather small, so if everything is organized and in its proper place, I work better, faster and more acccurately.
