Use a vintage necktie, lace scraps, ribbon, or embroidered fabric to make fancy headbands. Photo tutorial below.
Cut piece of tie long enough to go 2/3 around your head (mine was 15 1/2 inches).
Tie elastic cord into figure 8 measuring approx. 7 1/4 in. (I colored my elastic cord with permanent marker to match.)
Fold in ends of tie and position cord. Pin and (carefully!) try on. Adjust cord if needed. Sew.
