I copied Iris von Arnim’s luxurious cashmere sweater from her ads. The design is simple: Front, back, and both sleeves are completely straight. There are 4 braided cables over 12 stitches and 4 simple cables over 8 stitches with stripes of k1-p1-ribbing in between.
The same as in the original, the sleeves have become very long - no doubt due to the stretch in the ribbing. I’ll just tuck them in.
