I've made the Lacy Mock Cable sock and the Fluted Bannister sock in self-striping yarn. Both worked well. You can find those patterns at KnittingPatternCentral.com in the "Socks" section. Also, the Blueberry Waffle sock. That pattern can be found by googling it. There's a couple of variations out there, but they are essentially alike.
I did make the Broadripple sock in self-striping, which turned out well, but is a little tight going over my heel. I don't know if the sock shrunk slightly or if it's the pattern.
I really loved the Fluted Bannister sock. The pattern was easy but not to the point of boredom.
