This sock uses a simple 2 row stitch pattern that can be used with any yarn, including strongly variegated yarns. The pattern is suitable for men and women and creates a stretchy sock that has the advantage of being reversible. So wear your socks on either side or mix and match..
<p>
The pattern uses the following techniques:

• German Twisted cast on or other stretchy cast on
• Knit & Purl
• K2tog, SSK, P2tog
• M1
• Slip Stitch
• Pickup and knit through the back loop
• Broken Rib Heel Stitch
• Kitchener <p>

I have tested the medium size sock, but the large size sock has not been tested. Please let me know if you have any problems.

Make sure your pattern version is version 1.1. There is an error in the toe decrease round that was corrected.
