What you'll need:
a piece of fabric: 3x 10 inches
Cut your spare fabric (or whatever fabric matching the outfit you want it for) into a 3x10inch rectangle. fold in half (right side together) and sew it up. Turn it right side out and place elastic in the end of the band. Stitch together and repeat on the other side. I folded the raw edge of the fabric in before I sewed it together to give it a clean look.
