Gauge has been tricky for me with this yarn in the past, though. Knitting it up on size 0's is ridiculously dense: more like kevlar than socks. Knitting on size 1.5's often yields a sock that is comically large in the foot, though. Oh, and I should mention that only recently have I acquired size 1 sock needles. So for these socks, I knit the feet on size 1's and the legs on size 1.5's, and it worked like a charm! They fit nicely, and I'm still as in love with this colorway as I was when I first purchased the yarn back in 2007 (yikes).
Just like everyone else in knitterdom has told you, the Monkey pattern is a great one. There's a reason it's so popular: the lace pattern isn't too hard to read or memorize, it does a great job of breaking up any potential pooling in your variegated yarns, and the rest of the sock construction is straightforward. I will almost certainly knit this pattern again sometime, as I still have lots of variegated sock yarn in the stash.
