Step 20: Bracelet pattern
Then weave strands from the second color through. For me the first color was the black, the second the blue. You can, of course, just plait it and alternate strands. Use whichever method suits you, and make whatever patterns you like, the rest of this I show the wraparound method. When using that method it's best to make all the strands of the diamond plait emerge at the same "height" instead of in their normal diagonal. Weave the strands O1U1 with a lacing needle. The most basic pattern is the "bracelet". Go O4, then under 1.
Each successive blue strand goes under the next black strand and gets pulled up tight.
