Finally, weave another thread: 1 upper needle/1 lower needle, and then:

1) The first 1 needle and the second needle are woven together.

2) the combined needle and the third needle are combined into one needle,

3) Combine this stitch with the third stitch and the fourth stitch to weave a stitch, and so on.

Until the last 1 stitch, keep the thread 3cm before cutting. Finally, the thread end is picked into the braid on the side with the needle tip.
