Okay, so many people seemed interested, so here are the sweater socks I'm working on. I like to work toe up on long socks, because you can try them on as you go and get a perfect fit.
Here you can see how long they are already. I'm thinking of frogging back a little, because, since I've been working out my calves are a little bigger. Now the socks are a little tighter than I like around my calves. I think if I frog back a few inches and then go up a needle size they'll be more comfortable.

It's hard to tell in this pic, but these are the arch ribs. I have very defined arches, and I find socks to be much more comfortable if I put a 2X2 rib for about 2 inches right on the arch. This way, they don't bag in the middle of my foot or slide around. I like my socks to be a little tight.

Ignore my cabbage patch knees, and the blinding white skin. This is the sock from the top down. Coming along nicely, if I do say so myself!
