1. Start 7 stitches, knit according to the collar pattern, and after knitting 4 patterns, pick 20 stitches from the left to knit the washboard needle. After continuing to weave 13 pattern according to the collar pattern, weave 4 pattern at the other end of the collar. At this time, stop knitting the 20 washboard needles at the left end, and knit one needle at the left end in each row until four patterns are finished and 20 needles are collected. The remaining 12 needles on the sticking needle are collected at one time.
2. Pick 65 stitches from the collar and start knitting. Because it is a lapel, the front of the collar piece should be kept opposite to the front of the body. Start knitting according to the leaf pattern shown. After the leaf pattern is woven, there are 145 stitches. Knit three rows of plain stitches and one row of reverse stitches, then add stitches after three rows of plain stitches, and add 1 stitch every two stitches. After the needle is added, there are 2 16 needles on the lever needle. Then knit 5 rows of plain stitches, 2 rows of reverse stitches, add stitches after 5 rows of plain stitches, add 84 stitches evenly, and add 300 stitches altogether. Knit 7 rows of plain stitches, and then slit your sleeves.
3. Right side: 300 stitches are divided into three equal parts. Each piece 100 stitches, front and back pieces and two sleeves 100 stitches. When knitting, knit 50 stitches first, count 50 stitches as sleeves, add 8 stitches directly to the patch, then knit 100 stitches on the back piece, add 50 stitches to the patch, and then knit the remaining 50 stitches. At this point, there are 50+8+100+8+50 = 216 needles on the bar needle. Knit it to a suitable length according to the original sample, then knit several rows of washboard needles with 14 bar needles, and then close the needles.
4. Sleeves: Use sticky needles to string together 50 stitches with waste thread before, then stir up 8 stitches added under the armpit, and choose one stitch at each end, making a total of 60 stitches and weaving 5 patterns. After weaving to a suitable length, change the number 14 to weave several rows of washboard needles and then close them.
