Tutorial: How to make scrunchies from scrap fabric
Cut your elastic to 20cm.
Right sides (design side) facing inward, fold your fabric lengthways and sew the long free side to create an inside out fabric tube.
Turn this tube rightside out, and on the inside edge of one of the sides, place a few stiches to secure your elastic to the inside of the tube.
Grab the free end of your elastic and pull through the fabric tube so it scrunches up. Sew the free elastic edge to the other edge of the fabric tube in the same way.
You should end up with a length of scunchie.
Attach the two ends together by turning on end of the tube in on itself to create a hem fold, and place the other end of the tube through this to create a circle.
Sew a running stitch in a straight line down the middle of this join to hold in place.
Tada! Admire your scrunchie and start looking for more fabric scraps you can scrunchie-fy!
