Cut a length of cord and make sure both bracelet ends are even
Cross the two ends over each other to form a loop
Wrap one end around the other end and through the loop
Pull both ends to tighten the first knot
Repeat the same wrap-and-through motion to create a second knot
Slide the knots together so they sit close and form an adjustable closure
Test the bracelet by pulling the ends to open and close the loop
Trim any excess cord if needed
Seal the ends if the cord type requires it
