Now you'll start tying the alternate half-hitches by taking the working ends of the paracord, start with the left piece. Take the left cord under the two center cords and then back thru the loop of the left cord and tighten.

Now take the right side cord going under the two center cords and back thru the right loop and tighten. Again with the left, under the two center cords and back thru the left loop, etc.. continuing alternating the left and right cords.
