Done! I finished with about 10 days left in the KAL, but it took about four days for my sweater to dry after blocking. Last Friday was finally supposed to be pretty chilly, so I sewed my buttons on first thing in the morning and wore it all day. Then again all day Saturday (Sunday it warmed up again, but otherwise I would have worn it again-I get a little obsessive over new FOs).
Mods! Because there are always mods: I never keep track of how many stitches I pick up for the neckband, so that certainly isn't worked how it's written. Other than that, I shortened the sleeves by about 20 rounds because I thought they might get too long. It worked out perfectly, and they ended up just the right length.
