@Ana_541 I believe @Racoon (also well known as Masha knots) has a tutorial.
It is actually really simple. So say you are on row 1. You would make your bracelet like normal until you get to the last four knots. On the last knot instead of doing it on one string, do it on the last four together at the same time. So you would take the string that was supposed to be knotted on by the white and make a bundle on the edge and knot onto that.
