Huzzah! I have finished the mittens!
Pattern: Anemoi Mittens by Eunny Jang
Yarn: Jamieson's Shetland DK, 2 balls each in Natural and Seaweed (I think...the ball bands are in the other room)
Needles: I think the DK yarn was a bit thicker than what the pattern called for, so I used 2.25-mm instead of 2.5-mm needles to compensate. It kind of worked...the mittens are a bit narrow but nothing too painful.
Time: about 1 month for the right hand, 1 week for the left hand.
Mistakes that were corrected: most but not all.
