The spiral knot creates a beautiful helix or DNA spiral. It is especially well suited to use when creating plant hangers.
The spiral knot is actually a square knot, but tied repeatedly. The knot becomes offset, forming a spiral that twists down.
Start out by bending the left working cord, cross it over the filler cords and then under the right working cord. Pass the right working cord behind the filler cords and pull it through the loop created by the left working cord. Gently pull on both cords. Keep repeating the above steps until the spiral is the desired length.
