Fold one of the 3” squares in a ½” at the top and bottom. Iron these creases. Fold the square in half and iron the crease. You should have a sweet little rectangle with raw edges on one side. Zigzag stitch the ends of the two raw edges together. I like to zigzag mine over a few times for good measure.
Repeat with this process with other four squares. Next, you'll need to make the straps.
