I finally did it.
I got held up because I had to seam the sides a second time because I decided it wasn't small enough. I took off another inch total at the hem and chest so it ended up as 39" around. I couldn't do more, even if I had wanted to because it would start affecting the yoke. I'll need to think about that proportion when I knit my Wild Apple because I am broad shouldered but not chesty or very large in the middle.
As you can see above, there were two seams. I decided it was easiest to just cut up the middle to start.
But once I got started, there was no turning back.
Here I am in the improved Grey Mist Bohus. I love it all over again.
