The pink/blue socks are basic stockinette and knit with Jitterbug yarn from Colinette. As bright as they are I thought I'd forgo any possible pattern~
The Socks In the Cities Knit-a-long has monthly contests, and I won a skein of Fleece Artist Somoko. It's a lovely Merino/Nylon/Silk/Kid Mohair blend, and is a dream to knit with! Love the shimmer and the soft feel of this two-ply.
The pattern is really simple-- it's just traveling stitches on Stockinette-- a modified "Swirl Sock".
