Now take the end of the long piece of cord around to the point where the short end emerges from the knot. Work the long end through alongside the piece of the braid which emerges as the short end of the knot.
Follow the weave of this cord completely through the knot until your reach the starting point again, making sure you lay the cord so that it stays either inside or outside of the curve you are working on. Keep the cords side by side, do not allow them to cross over the other cords.
When your reach the length of short cord that signifies the start/end of the knot, continue to braid and weave around again, making sure your cords follow through the knot side by side. Continue to weave cord through following the weave for 4 to six complete circuits, until the rug has very few gaps.
