Cute design with simple principle "Just Braid".. !
You’ll need 3 strands of twine cut into one yard pieces, 18 small brass hex nuts and a bit of dexterity.
Gather the 3 strands of twine and tie a knot at the top, leaving about 2 inches of slack. Start braiding. At about an inch of the way down, you’ll begin braiding in the nuts. Before you braid the far left strand over the middle strand, thread on a nut, push it against the base of the braid, and crossover. Depending on the thickness of the twine, you can wrap tape around the bottom tips to prevent the twine from fraying.
Keep your thumb at the base of the braid, holding the nut in its place. Before you braid the far right strand over the middle, thread on another nut, push it against the base of the braid and crossover. Again, hold your thumb tightly against the base of the braid, keeping the nuts in place. Thread another nut onto the far left piece and crossover.
Repeat the steps, by threading the rest of the nuts to the outer pieces of twine before they are crossed over. Thread, cross, thread, cross. Finish the bracelet with another inch of braided twine and a knot.
