You need a pendant with a hole large enough for the cord to be doubled up through.
Fold your length of cord in half.
Thread the folded end of the cord through the hole of the pendant.
Loop the ends of the cord through the loop created by the folded cord.
Pull on the two ends of the cord.
Continue pulling the ends of the cord until the knot it taut around the pendant.
Congratulations! You have successfully created a Lark's Head Knot around a pendant.
