This is Unique Sheep's Verve in Dusk Dark. It makes me think of Van Gogh's Starry Night. I love how fast a shawl works up when the rows are short.
Don't worry, I'm still working furiously on my Boston sweater, but after finishing the body, I haven't had some uninterrupted time to pick up stitches for the button band. I plan to do that this weekend, though, and then it's smooth sailing again.
