Take the sari ribbon and place it under the beading thread so that both lengths are even on each side. Take the left hand ribbon and pass over the beading thread, bring the right hand sari ribbon over the left and pass under the beading thread and up and through the loop that has formed from the left sari ribbon. Pull up tightly to the clasp. This is the half square knot. Continue with another 2 half square knots making sure you use the left side ribbon each time.
