I pinned a corded anchor bracelet on Pinterest last year. Since that time the blog (with instructions or sales info) has been removed. I have been asked how to make the bracelet and I don't know. But the more I look at it, I believe it could be simple enough to recreate. So here are the steps I would try:
1) cut two lengths of cord a little longer than the circumference of your wrist.
2) fold one length of cord in half and apply a crimping end-cap with a ring on the end (maybe using glue inside the cap for a more secure hold) then using a jump ring attach the anchor charm to that loop. Set the first loop with anchor charm aside.
3) fold the second length of cord so there is a tail of about 3-4 inches, place a crimping barrel over the loop and the opposite free end (so there are three cord widths inside the crimping barrel and a loose tail sticking out. I would NOT crimp the barrel at this point.
4) intertwine the two looped cords (like you would intertwine two rubber bands)
5) wrap the intertwined loops around your wrist, close the looped tail over the anchor, adjust until it fits your wrist but can also be taken off (by unlooping the anchor), trim the tail, and crimp the barrel to secure everything.
I'm sure there's probably an easier way of doing it--but that's probably what I would try to do to duplicate the bracelet in the photo. Hope that helps.
