@dojac I'm not sure if it works like this but in the first row you take the 2 middle strings, in the second the four middle strings, then 6 strings, 8 strings, 10 strings and then 12 strings. I would have to try it out myself to to give you a certain reply.
@NutEllah this pattern was meant to be a pattern for the "knitted" bracelet. Craftanatic on YouTube has a great video on it. But people so far have instead knotted diagonally.
