Sihnon Cable Scarf
The cables in this scarf are created by using 2 cable needles. Reading my blog post (http://smariek.blogspot.com/2008/10/sihnon.html) might give you some insight about the cable twists and this understanding might make it easier to work the cables.
Cable patterns tend to pull inwards and thus require more yarn than a plain knit/purl pattern. This particular cable is “yarn thirsty”, so plan for more yarn than you think you might need.
Stitch patterns used in this scarf are mentioned in the Pattern Post here:
