Turn the lanyard over, so the other side of the knot is facing up. The working strand now on the right side will be brought under the cords, back up and down through the parallel strands of the knot as shown, then tighten. And continue this process, flipping the lanyard over, taking the right strand under and back up around and through the parallel cords, and tighten... Continue until you run out of cord or reach the cross knot.
You'll now trim off any excess cord and quick melt the end of the strands to prevent fraying to finish.
