STEP 7 – STRAPS AND LOOPS:  To make the back loops, cut two 2” (5 cm) pieces from the neck straps. On the BACK, sew the loops, starting 1/4” (6 mm) from the top border. Make sure to back tack.  Fold the strap and sew again, just on top of where you already sewed.

Insert the neck straps on the back loops, using a safety pin. To add the cord ends (optional), cut the ends of the straps diagonally and insert the cord ends.  Using a pin to pull the strap is helpful.  Tie a knot on each end and cut the remaining close to the knot.
