A really beautiful art project can be made with scraps like you have between two sheets of soluble stabilizer. You put all the scraps and any leftover threads, yarns, etc. inside completely covering the stabilizer and then quilt/sew all over the top back and forth until the quilting is completely covering the scraps to hold them in place.
When you gently wash out the stabilizer, you have a very interesting piece of new material for another project. Batiks are great for this since they do not have a distinct wrong side.
