You can make "Wonky Fabric" with them. Cut out some 12" or so, squares of clean newsprint and just start sewing them down from one corner to the other. Or from one side to the other. You don't have to watch your seam width, so it goes quickly. Just be sure all the raw edges are covered. You can sew short ones together before you sew them to the paper. I do one color range at a time. After you're finished, leave the paper on the back and store them in new pizza boxes. When you get ready to use it, you can then cut it into smaller blocks and put sashing between it for a real scrappy quilt or when you need a cute applique, you can cut it out of your wonky fabric and it looks like you pieced it especially for that. A lady from Australia showed how to do this on "Simply Quilts" a long time back. I use fleece scraps for stuffing dog beds for the animal shelter, but the fabric ones make nice throw pillow stuffing.
