Knitted Sweater

I cast on 42 stitches for the sleeves, knitted ribbing 1*1 for 6 rows.
I knitted in turning rows, as I initially did not plan to knit in raglan, you can knit the sleeves in the round right away.
Then I evenly added 23 stitches. In total, 65 stitches (distributing the stitches for our pattern: 1 knit, 2 purl, 22 pattern stitches, another 22 pattern stitches, 15 pattern stitches, 2 purl, 1 knit)
I knitted 3 repeats of the pattern in height on the sleeves!
⠀
I cast on 166 stitches for the body, knitted ribbing 1*1 for 8 rows, distributing the pattern (the back has 83 knit stitches / the front has 83 stitches, of which 10 are knit, 63 are the same pattern as the sleeves, 10 are knit)
In height, 3 repeats!
Then we join the sleeves and body (I left 6 stitches for the underarm) and knit according to the pattern with decreases every other row to the height you need, knitting the neckline with ribbing 1*1, sewing the underarms!
