No i'm not sure that is the knot, it looks similar. It could also be a square knot. The knot is repeated over and over to make a braid. I am really not sure how to terminate the crown knot to make it into a loop. If you use a square knot it will terminate into a loop. Try this link for a square knot,

If nothing else you can have some paracord zipper pulls. Sorry i'm knot more helpful on this, decoritive knots are knot something i've done alot of. If you have a good library near by you might want to stop in and see if there are any books on knot craft. Good luck.
