I know some people swear by knitting from two balls, but wouldn't that just dilute your pooling? I want an easy mindless sock for office knitting - I can't be juggling and untangling two balls. I knew from the beginning that I wanted to do nothing more than a simple rib-style stitch. The first 20 rounds are in 2x2 rib. The next 10 are an experiment that I decided not to continue (but did not rip back to that lovely dental floss, because I think you can hardly even see it). After that I went into what Charlene Schurch calls "uneven rib." It goes like this:
Round 1: *K2 P2*
Round 2: K1 *P2 K2* ... until one stitch left, then knit it
The result kind of reminds me of the garter rib I used in this sock. Still very simple, but not quite the drudgery of 2x2 rib.
