doctor who?

I've decided to take up knitting (because I like hats and scarves and sweaters, and I like being crafty). I've just barely started, but I think I'm getting the hang of it. So Adam has asked for a scarf lilke the one worn by Dr. Who in the eponymous show on the BBC. At least I think that's what it is. I've never seen the show, and I have no idea what a Dr. Who scarf is. Enter the Internet. I now have the "official" BBC pattern for the scarf. And I've seen pictures of scarves online. But I'm still not quite sure how this thing is going to work.
