That's pretty much what I'm knitting these days! If you check out my Rav progress bars, you'll see that all of my currently-listed WIPs are either socks or scarves. Socks are perfect for the bus, and scarves are good for TV and movies. I've actually got a pair of wristers going that I haven't added in to Rav yet, but those are, so far, no different than socks. Instead of turning a heel and making a foot, I'll leave the end open and make a thumb!
Most recent pair of socks that I finished:
Oak Ribbed Socks
What's neat is how the stripe patterns line up:
It was two separate balls of yarn, and apparently they were either wound in opposite directions, or I started with a different end each time -- too funny!
Also, these are the socks during which I figured out my personal cure for SSS. I almost finished the first sock on one of my trips this summer, but I didn't want to graft it shut while I was away. That would be a recipe for disaster! I still didn't want to graft it after I got home, so I started on the second sock, and it went so quickly. It took significantly less time to knit than the first, and much less time than a second sock usually takes me. So I think my new plan is to never finish the first sock in the pair...we'll see if this works!
