Crochet Ripple Pattern

I started my first crochet project, a scarf in the Noro Kureyon yarn. The first time I did it, I didn't look at the directions closely enough. The pattern starts on one line, then goes to a second, and only the second line is repeated. But I assumed both lines were repeated, for the front and the back. Other than that, though, the pattern is really easy. I think once you know how to knit, crochet is a lot easier. The pattern will probably be more clear on this scarf once the yarn is lighter in color.
