The square knot is
tied by taking the right (red) knotting cord and passing it over the two core
cords. Now take the left (blue) knotting cord and pass it over the right then
under the core cords and up through and over the right hand knotting cord. This
first half of the square knot is called a half knot and a series of these knots
will cause the band to spiral to the left. Now take the right hand knotting cord
(red), which is now on the left, and bring it over the core cords to the right and
pass the left hand knotting cord (blue), which is now on the right, over the red
knotting cord, under the core cords and up through and over the red cord on the
left. Pull tight and push up.
