Here's a like to a better photo on Flickr.
The pattern calls for a left twist stitch on the opposite side of the scarf (you can see it right next to the seed stitch boarder), which is meant to provide some design interest on the wrong side.
For the longest time, I could never figure out how to make a left twist, and of course, I didn't want to ask anyone. Finally....I thought of YouTube!! And sure enough, I found a video to teach me how to do this stitch. YouTube is a patient teacher and doesn't complain if you need to repeat more than once.
The video shows that the first stitch is dropped, but when I tried it, I kept pulling out that stitch. I find it helpful to hold the first stitch between my thumb and forefinger as I knit into the back of the next stitch.
I'm enjoying the scarf, which has enough twists and turns to keep me interested, but I have the urge to knit a sweater next.
