Well, I decided I didn't like the sc ribbing after all, so I frogged and started over. BOO. The good news is I'm most of the way finished with the toe, and have to say that these are some ingenious socks.
They're really curly at this point, so I had to kind of pin them down to get a good picture. But seriously, clever right? That's the whole cuff, the top of the foot, and the first part of the bottom of the toe. So the seams go up the sides of the foot then up the back of the cuff, where there's less pressure on them. Neat!
