This is a fun-to-knit cushy reversible scarf pattern. The technique is not hard once you get the hang it.

For a wider scarf, cast on an extra 8sts for each cable you want to add. The set up row adds 4 yos per repeat, which brings you up to 12sts per cable. At the original gauge, each added cable will make the scarf about 1.6 inches wider.
