Sleeveless with some waist shaping (decs then incs) on the back in addition to the cable shaping on the front.
After blocking: Even with the extra decs in the armhole (see below), I didn’t like how the armholes fit. They “fit,” but I wanted the back of the armhole to scoop into the back of the sweater more. Surgery: I unravelled the ribbing around the armholes and picked up 1 to 3 sts further into the back, then reworked the ribbing (BO with JSSBO). To reduce the seam allowance, using half the thickness of a CC strand of Cascade 220, I zigzagged along the seam allowance with my sewing machine (!!) and then trimmed it (!!!) and secured it all by hand (because I had over-trimmed in a couple of places) using needle and thread. Terrifying, but it worked.
Swatching
Pre-blocking: 4.5 mm: 20.75 sts and ~30 rows per 4”
After wet blocking: 20 sts and ~29 rows per 4”
I decreased 1 st in from the edge instead of 2. Also, I decreased in the armhole more aggressively than in the pattern (2 extra decs every other round before beginning the St st) because I would be adding the ribbed border. I could have done a couple more in the back (every round, before the every-other-round decs — or, easier, just BO 1 or 2 more sts on the back side before shaping the armhole, so it would have been more cut into the back), but this is okay.
I mitered the V in the neck band by adding an extra stitch in the middle when picking up sts, knitting that st on every round, and working a decrease in either side of it (so the middle 3 sts alternated each round from p-k-p to k-k-k). On the knit rounds, this looked like: k2tog, k, ssk. On the purl rounds, this looked like: ssp, k, p2tog. The rest of the sts in the neckband were normal 1x1 rib.
4.5mm for body and bottom ribbing. 4mm for neck finishing and armhole ribbing. BO’d with Jeny’s Surprisingly Stretchy BO.
