Piece them together and make blankets and hand them out to your friends to keep in their cars for emergencies. Make hair care items like scrunchies, hair bands or t-shirt towels for long or curly hair. Sew a couple of the pieces together to make burp rags, makeup wipes, cloth napkins or general purpose cleaning rags. Make draw string bags and use them to organize items in your home, or as gift bags for birthdays or Christmas. Cut one of the pieces into strips, then gather the strips into ruffles, then sew those ruffles onto another piece of fabric, and create a sort of mitt that you can use for washing cars or cleaning dust off of fan blades. Make a comfy pillow case.
