Wash Sweater, back on track?

I worked on the Wash Sweater for about a month, then stalled out two months ago, when it came time to plan the sleeves. Not that the sleeves will be hard, but some decisions are required, and whenever I tried to summon up the energy to make these decisions, I was struck by this stark fact:

I don't have enough yarn to finish.

I got the yarn from Mary who was stash-busting. She got it from Handpaintedyarn.com. When I started the project, there was no more to be found in this color ("Sea Foam," which you might
think would be green but actually is the dirty beige color that real sea foam tends to be). I thought I might try to find something close, then dye whole garment when it was finished. But even better: when I went to the site this morning, there were three skeins to be had.

So. Back at it. I've been keeping my planning notes in a Google document, which I just made public today, so you can follow along if you want.

Meanwhile, Dodger reminds me that, if I decide not to finish, he'd be perfectly happy to make use of the work-in-progress.
