Tie two strings around the neck, doubling the length.
Pass a brass wire through the knot, twice the length of the string you wish to decorate.
Wrapthe brass wire around the string ina spiral, threading either a spinning top, two seed beads (one spiral apart) or a round bead.Finish the end of one string by threading a round bead.
Once the four strings from the knot around the neck are decorated, tie a knot with two of them and arrange the other two (the string is stiffened by the brass, so it's easy to give it a shape).
