Sized to fit a man’s foot 9-11 (for a snugger fit, simply go down one needle size)

When I asked my dad what he wanted for his birthday he simply said, “Socks”. Given that he is terribly practical, I didn’t think much on it and figured that a trip to the local sportsman’s store would suffice. Exactly one week before his birthday it dawned on me: Oh my god. He meant he wanted a pair of knitted socks! With only a week to spare, and very little time to knit, I whipped up and knit these quick and simple socks. The addition of the seed stitch “ribbing” gives dimension to the variegation of the yarn, while ensuring that you won’t go insane from boredom.
