4mm: Alternate cast on (as suggested by the pattern) +1st (to have an uneven number of st) and twisted ribbing
K1 for selvage, k1p1… k1, k1 for selvage
Starting on size M but will have to decrease to size S around the bust/sleeves/shoulders so I’m adding a column of purls to act as a fake seam…
Adjust st numbers on the 1st row of pattern: k1( Selvage), sts for pattern front, p1 (fake seam), sts for back, p1 (fake seam), sts for front, k1 (selvage)

Sleeves size S: also added a p1 (fake seam)

No idea how many st I picked up for the button band… I adjust on the first row. K1 for selvage (it will roll neatly towards the back) k1 p1… k1, k1 for selvage.

The bind off for the neckband was new to me. I had a look at the tutorial on Alice Hammer’s website and managed to find a video on youtube with Eng and Fr subtitles showing the technique link
