Step 1: Tying the base
Next, take one strand and fold it under the strand to its right. Continue doing this until you reach the sixth loose end. Feed the last running end through the loop you created with the first strand. The idea here is that you're making a wide base, and the loose ends should all point 'up' with the loops on the outside. Tug, twist and try to get an evenly tightened knot, but don't waste a lot of time. At this point there isn't a lot of cord to really hold the knot together.
In the next step, you'll do the same thing in the opposite direction to make a wall of nested bights.
