What are the sentences describing the action of knitting a sweater?

I saw her holding a needle in her right hand. She kept poking forward and left, picking up all the threads from the left hand needle to the right hand needle. This action is indescribable. After a while, the needle in the left hand was empty, and my mother changed the empty needle to the right hand to continue knitting. I saw the thread ball gradually getting smaller, one was used up and another was changed.

Take a pullover as an example: knit a raglan sweater from the collar.

1. Start knitting 72 stitches (the number of stitches you want to knit depends on the thread and the size of the sweater collar to be knitted).

2. Weave the collar to a suitable height and mark it with lines: 12 stitches on the sleeve, 2 1 stitch on the back piece and the rest on the front piece. Add one stitch every other line on both sides of the mark (add 8 stitches in 4 places * * *, leaving 2 stitches in the middle).

3. Start knitting 12 stitches from the back (front), then return to knitting 16 stitches (back), and then return to knitting 20 stitches (4 stitches on each side, that is, 4 stitches more than the previous row). Don't forget to add stitches (now there are 4 stitches in this row). Repeat this process until the sleeves are woven into 12 stitches.

4. When knitting the front piece, you should bring 2 stitches on each side (instead of 4 stitches), and now the number of stitches in the front and back pieces should be the same. You can knit in circles until there is about 1 inch left in the middle of the front piece (if you knit a round neck cardigan, you won't knit in circles), and the front piece has been knitted. (The needle has been added to the marked position)

When the body and sleeves are fat enough, put the sleeves on and knit them down, so there is no need to add needles. Finally, knit the sleeves.
