I'm a scrap quilter with literally thousands of remnants. They're sorted by color (and sub-color) and are "displayed" in hanging baskets from the closet rod. I took the bi-fold doors off the closet. Solids are in a separate open tote on the floor of the closet. Squares from swaps (OMG how many!) are filed by color in two filing cabinets with hanging files. Jelly rolls and strips are stored in plastic shoe-box size totes in a bookcase that also serves as a side table for my cutting area. Yardage (very little) is in a separate tote in the other closet in the room.
