2. Then, the knitting length is (from cuff to armpit), which is basically the same as the length of sweater from hem to minute hand. Then, start with 4 stitches on both sides, and then continue knitting upwards. Take a stitch every two rows (both sides are consistent), and weave about 1 inch. Start taking a stitch every five rows (both sides are consistent).
3. Finally, the length of the knitted armhole is the same as the length of the armhole on the sweater, so that the needle can be closed and a single sleeve can be knitted.
4. Finally, fold the sleeve (the reverse side is outside) into sleeves, align the cuffs neatly, and sew from bottom to top.
