Before sewing the "finishing seam", stop the machine, and remove the hoop without unhooping the design.
To add a small strap for hardware, cut a piece of non fraying fabric that is 2” long and ½” wide, or cut a 2” long piece of ribbon or cord. Fold it in half, and place the looped end on the inside of the pouch (so the raw edges hang over the edge). Tape it in place over the embroidered details, and make sure the loop will not get caught in the finishing seam.
To make a whole wrist strap, do the same thing,
but with a cord 8”-12” long, and fold the looped end up so it is
condensed over the detail embroidery.
