Construction:
This halter is worked flat from the top-down. The i-cord straps are made first to have at the ready, and then a folded collar is worked that will hold one of the i-cords. The top is shaped using increases on either side until stitches are cast on for the back, which are worked in a 1x1 rib and where the holes for the other i-cord strap are made. Once the back portion is done, the decreases for the front are worked until no more stitches are left. A nice little border is added to the bottom front as a finishing touch.
