I've been stash raiding for the yarn for this and have come up with Blue Moon Fiber Arts Socks That Rock Lightweight in Sweet Pea and Pining 4 Ewe and Malabrigo Sock in Lettuce.
Having a closer look at the pattern I noticed that I'm short of the Sweet Pea that I need for the background. So, I'm going to cast on and keep my fingers crossed that someone on Ravelry will be destashing a skein!
I'm off to look for some needles as I've got just over an hour and a half until the opening ceremony starts. (As you can see I'm SO prepared for this)
