I started a pair of socks on my recent trip to Hawaii. I ripped out the first attempt because size one needles were too large. I found a pair of size 0s at The Needlework Shop in Lahaina, Maui, and started again.
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.
