Tried a new sock yarn, Reggio, sport weight, and as I didn't know how the skeins would last, I started with provisional cast-on and worked the foot down and then the ribbing up. Good thing! The socks are shorter than I would have liked, but a nice wardrobe basic. Once I figured out how tall the sock could be, I knit sock #2 in the normal sequence, from the top all the way down.
