From the Knit Picks Website:

This cuff down pattern knitted on circular needles is really very simple-there needn’t be any twisting of the yarn along the back as long as you carry loosely. Stroll Hand painted as the contrasting color gives these socks the dazzle that color knitting is all about.Contrasting Stroll solid colors offer a more conservative look for the man that you knit for.

To size the pattern up or down, change to a smaller or larger needle - the yarn requirements are the same!
