From Blue Moon’s website:

“Brioche stitch patterns make some of the most stretchy, cushy, and comfy fabrics around—perfect for socks to wear around the house on a lazy Sunday morning! These Brioche Socks, worked in a simple two-color brioche rib, are reversible: the color that adorns the knit ribs on the ‘outside’ glows from the purl furrows on the ‘inside.’”

2 skeins Blue Moon Fiber Arts® Socks that Rock™ mediumweight, in contrasting colors. (You will have yarn left over for another pair.)

US size 1 (2.25mm) needles, or size to obtain gauge
US size D (3.25mm) crochet hook and waste yarn, for provisional cast-on

Also Needed:

• Clip-on stitch markers or waste yarn
