Errata!! The pattern had a mistake.. sorry! However, I have fixed the problem and uploaded a new pdf with the corrections and some additions to help make things clearer, so please download the updated pdf. Hope this helps, sorry for any inconvenience.
I created this pattern from a combination of cable designs. The middle cable is called the Vine and Twist from the Harmony Guides 450 Knitting Stitches Vol. 2. The two outer cables are regular 6 stitch cables. I also added a 1 inch moss stitch border to help keep the scarf from curling and it just looks nice.
