I finally cast on for my first Summer of Socks '08 project on Sunday night. My original plan was to use 2 circulars, but one of them is currently in use for a baby sweater. I had a set of 5 size 0's double pointed, so I'm using them. I am finding I like 5 easier than 4. The pattern is Yarn Harlot's basic sock pattern and the yarn is Lion Brand's Magic Stripes "Denim Stripe"
