Designed to coordinate with Sun and Sunshine.
If Sun will follow this stitch pattern, work the last row without the 1/1 cable crosses; replace each of them with two knit stitches instead.
See blog post for the designer's preferred double decreases (it's a slight difference, and not strictly necessary), and for more information about how the stitches were designed.
Shown with a cast-on count of 36 stitches.
