I'm thinking I'm done! Just bind off, and...just kidding. But mostly so far, so good, although I'm going to rework the sleeve cuff; I was thinking I would do a fairly snug ribbed cuff that would be best worn pushed up on the forearm, but this one is too tight and unyielding.
The color of the yarn is better represented in the second photo. I reworked the neck four times using various edge treatments, including a twisted cable rib, but in the end I decided simpler is better. I also blocked right after casting on stitches for the underarms, to make sure I wasn't misjudging the final gauge; if you look carefully, you can see the transition between the blocked and unblocked fabric.
