All you will need is: 3 strands of cotton butcher’s twine cut into a meter of pieces, 18 small brass hex nuts and a bit of dexterity.
You will gather the 3 strands of twine and tie a knot at the top, leaving about 2 inches of slack. Start braiding and at about an inch of the way down, begin braiding in the nuts.Your repeated steps will be: Thread, cross, thread cross.
Your finished product will look like this.
Note: your bracelet should wrap around your wrist at least 2 or 3 times. Trim it to your liking.
