Hey there! Did you ever figure out what the stitch was? On the day that you posted this question, I decided to give it a try myself. I used two strands of Vanna's Choice held together throughout. I did two rows of K1P1 followed by two rows of garter stitch. My scarf came out fairly close to what was in the picture. It just wasn't as full as the ones pictured. I bet that it would be thicker if I had used a bulkier yarn. I will post a pic of it when I get home.
