A top-down pattern worked in the round except for the diamond argyle portion, which is worked flat and seamed up the back.

A great pattern for intermediate sock knitters that want to give argyle a try - complete with photo tutorial and tips for working intarsia and how to seam up the back.

This is a one-size-fits-most pattern, but by working in a slightly larger gauge (on US 2.5 or 3 needles), a larger ankle and foot circumference can be achieved using the same yarn.
