I'm using Lorna's Laces Shepherd Sock wool in Aslan (beige, lilac, light blues), which I won in a drawing at the former Knitty Gritty.

The pattern is from Wendy Johnson: her toe-up feather and fan sock pattern (.pdf).

Sock has been knit while on Maui beaches, in the condo, and in the airport. The first attempt on too-large needles kept me occupied on the flight over.
