Comments: There seem to be a lot of these "yo, knit X stitches, pass yo over X stitches just knit" type of patterns. This one varies slightly because you work the yarn-over backwards, bringing the yarn over the top of the right hand needle, from back to front (as opposed to bringing it around between the needles and then taking he yarn from front to back). I'm not sure you can see the difference on the front, but its much more obvious on the back - it looks almost like a line of slipped stitches. (I'm not giving a picture, to tempt you to try this out for yourself!) :)
