Finally finished. I used Lorna's Laces Shepherd Worsted in Black Purl (7 skeins).
Blocking. For details, see my Ravelry entry. I had a few problems with this one.
This is how the neckline looked when I knitted it per the pattern. I think unless your neck is as big as a tree trunk, you might also have to rework the neckline. My best guess is that the grading is off. While people's bodies may grow fatter, their necks don't change nearly as much as, say, their busts.
I'm glad I stuck with it, I really like the finished piece and I think I'll be wearing it.
