Men's sweaters are thick loops knitted with 334. It's time to divide the armpits. How many stitches do you want to keep and then reduce? There are still a few stitches in the shoulder! How much should I leave at the collar? It was woven from small to large. Generally, one side of the sleeve is left with 12- 16 stitches. According to people's fat, sew more stitches and less stitches. First the front film, then the back film. The penultimate stitch of the front piece is deducted by 12- 14 every two stitches. For the back film, just subtract one button every three or four times and 5-6 buttons. Take it out and see if it's a round neck or a chicken collar. If it is a round neck, leave about 40 on one side of the shoulder. The collar should be in 120- 140. For reference only.
