This is a pattern by Marlo Cairns and also the start of our Winter Week. I do not have any wrist warmers, but I imagine they would be great for a cold house when you need to get things done and need to use your fingers. I bet Lisa could use these in Korea, she said it is pretty cold there.
Updated 12/1/2011: These bad boys are going to my little (okay she's totally 15 and no longer little) cousin for Christmas this year. Cute little warmers they are. I ended up not putting in the thumb or contrasting yarn because I liked them how they were. I like simplicity, people.
