I'm a big believer in re-use and re-purpose. I store pending projects in the clear zippered bags that sheets, pillowcases, and draperies come in. Then these projects can easily be stacked on a closet shelf or in a drawer. For fabric that is just part of my collection I like to sort by color and type (florals, batik, plaids, etc); these go into a glass doored bookcase. Fat quarters go in drawers and arranged by color, batik fat quarters go in separate drawer.
