1. Going from left to right, bring the left most yarn over the 2 centre yarns (anchor cords) and under the right most yarn.
2. Moving back to the left, bring the right most yarn under the anchor cords and through the loop formed by the left most cord. Pull on both ends to tighten knot. You will get a half knot.
3. Repeat the half knots several times to result in a spiral. To ensure that the spiral is even, tie 4-5 square knots, and rotate the sinnet. Continue until desired length.
