@jen-jen nothing really, basically the "^" is against the skin which keeps the bracelet in place while wearing it. There is another bracelet with the same clasp I'm currently wearing for 3 months and it never fell off.
@jen-jen I make the clasp with iron-wire and wrap floss around it. then just knot the bracelet against it. the triangle is the end, I usual glue or stitch it on the back.
@sage-wolf well there is a similar one but not exactly, the one I made has wide/small or small/wide in each X. this: #111759 has wide/wide and small/small in each X. But honesty it is veeeery easy to make a smaller version of it just by looking at it the pattern or covering half of the pattern. There isn't a need to make a new pattern with less or more strings since it's easy to understand/follow
