First, prepare wool and labels. Both direct and loop labels are acceptable. Here is a demonstration of how to start a double-breasted sweater.

Let's get started, just press and hold a button.

Put a stick in the buckle and tighten it.

Then continue to buckle this label until it is enough. Here, for demonstration purposes, only 12 buttons are proposed.

Let's take knitting one reverse and one right as an example: put a sign in the first buckle and bring the wool to it.

Pull the wool with the sign, tighten it, and retreat from the first sign.

Bring the wool up, and the second sign will go up diagonally.

Wrap the wool around the label and pull it down.

Now step back from the first button to the second button, thread the thread to the end, and repeat the operation of the first button above.

So a bottom floats and weaves again and again.

Until you knit to the height you need.
