Fabric scraps can also be made into Paper. We live in Appleton WI in the heart of the valley with paper mils. One of the field trips I took with our youngest was to the paper museum. We made paper form scrap paper but were shown paper from jeans. Look into it or offer your scraps up for crafting on freecycle in your are. Some schools like them too for art and other projects. My kids like them for funky modern art pictures.
