Fold B across the two core cords. Align A on top of B. Bring A under the core cords and through the arch made by B.
Pull A and B to tighten. One right spiral knot is complete.
Repeat steps 1-2 using A. Continue in this manner, making sure to always bring the right cord over the core cords.
After making four or five knots, hold the core cords taut and push the knots up to tighten. The knots will start to twist as you continue working.
