3mm leather
 glitter cords
 a 6mm magnetic clasp for leather

To start, measure your wrist.

Cut a leather strip to size.

Cut 3 cords about 35cm each.

Tie the 3 cords and the leather near the edge with a polyester thread like sewing thread.

Start the 3-strand braid with the cords...

Continue braiding until the same length as the leather, then tie them together.

Cut off the excess cord.

Then place glue in the clasp and insert the cords together.

Wait until completely dry before wearing your creation.

And there you go! Beautiful creation!
