In the Square Knot Sinnet only the outer strands of cording are worked. There can be none, one, two, or more anchor strands.
1. Make a Half Knot, with the left strand passing in front of the anchor strands.
2. Bring the right strand behind the anchor strands so that the anchor strands are enclosed in a loop.
3. Make another half knot with the right strand passing in front.
4. Pull tightly.
