I saw her make them on Knitty Gritty, too, and thought they were amazing! I haven't bought the book yet (I didn't realize it was out already!), but plan to even though I've never knit a pair of socks yet in my life. Knit plenty of other stuff, just never interested in socks until I saw these.
ANYHOW, they look great and I'm so happy to see that someone's knit them! Great job, and I agree with kelliz, lil' baby legs are adorable.
