Stealth Argyles--Making Progress

I've been traveling to teach workshops more that usual, which has definitely cut into my knitting time. But I am making progress on Eunny Jang's Stealth Argyles.
I've just changed to larger needles for the upper leg. If I could focus on the sock, I could probably finish it in a day or two, but I expect that things will get in the way and it won't be done until next week. Too bad. I really like working this pattern and I'm anxious to see how the argyle motifs look when I have them on my feet.
