The name of these socks was inspired by the color of the yarn I was using, and a fond memory of swimming in cenotes in Mexico. Cenotes are fresh water lakes made by the collapse of underground caves and then filling up with ground water. There are many of them on the Yucatan peninsula, and the water is as blue as these socks.

This pattern is written for knitting in the 2-circular needle method but can easily be converted to other methods.

It features a 2 by 2 ribbed cuff and a very simple stitch pattern that is easily memorized that I found in a very old sweater pattern. It’s slip stitch, but with garter in between it ends up being very stretchy. Written for a womans medium sized foot (size 8-US shoe), it requires 100 grams (3.5 oz) of fingering weight sock yarn and size 2 needles.
