You could have a quilter's rummage sale - maybe have some grab bags, coordinated bundles of fabric tied together, fat quarter bundles, etc. Just be prepared for the fact that you probably won't get the same amount of money as you paid as everyone is looking for a deal. I just went shopping in my stash and made a whole quilt - top, batting and backing and all in my closet. I plan on doing a lot more of this kind of shopping.
