5. Sew edge down for a clean finish, I sewed three lines, ¼" apart so the ends will be more sturdy and it looks more polished.
7. Sew right sides together with a ¼" seam allowance. If you think the finished cover will be too big for your strap, you can make a wider seam allowance to make the cover thinner. Keep in mind you want the cover about half an inch or so bigger than the strap, so its easy to slide on and off.
