@K4tyKat you do triangle ends the same way you shape the rest of the bracelet. The band has a width of 6 knots, so you need to do one row of 4 knots and one row of 2 knots. You always hide the unused strings in the knots at the edges.
@razilyaaks it is a shaped bracelet. If you want to know how it is done, you can check out Alex's Innovations' video on the shaped evil eye bracelet. Basically what you do is, you leave the knots out that are blue in the pattern and hide the unused base strings in the edge.
