STEP 1: Measure your braided cord to fit your wrist, allowing for the clasp. Put some sticky tape around the cord and cut in the middle of the sticky tape so the braiding does not unravel. Alternatively you could stitch through the cord to secure the braid.
STEP 2: Repeat step 1 to create another piece of braided cord of the same length.
STEP 3: To complete, separate the starlight clasp. Glue both pieces of braided cord into the clasp using fevi kwik, and leave to dry before closing the clasp.
