The steps are as follows:
Start knitting 240 stitches from 13 stitches, then weave double threads from front and back panels 1.5 inches, and weave 120 stitches from front and back panels respectively. Add a flat knitting needle to the back panel, which is about 1.20 stitches, enough to open and close at 1.05 feet, flat 5 stitches, then 2-2-2, 2- 1-5 92 stitches, open and close 4.5 inches: flat 36 stitches, and then 2-2-2, 2-66 stitches. Add one needle to the left and right of the front piece, and the number of other needles is the same as that of the back piece, 2.5 inches from the shoulder. Digging collar: sew 24 stitches flat, and then sew 23 stitches on the shoulder of 2-3- 1, 2-2- 1, 2- 1-6, which is long enough to be combined with the back piece.
Double thread 1.5 inch is woven from 50 stitches on the sleeve and evenly added to 60 stitches. The pattern arrangement is 2 1 stitch +2 groups of patterns (2 upper stitches +8 stitches +2 upper stitches +4 lower stitches +2 upper stitches), specifically, +2 1 stitch and 8-/kloc. Sew the front and back panels, sew the sleeves, pick up the collar, knit a row of needles, a row of needles, double thread 15 rows, and close the needles.
