After speaking with a couple of people on the Yahoo groups sock list, we figured out where I was misreading the pattern. It was sort of implied that there was a knit row in between the increase rows so I wasn't increasing gradually enough. Added to that, I needed to go down a needle size to be more in gauge. They look pretty good now, don't you think? I'm pretty pleased with them so far. We'll see how the rest of this first toe up sock goes.
