Corcair is a rib variation that is very stretchy, I would take that into consideration when choosing a size.

The design has been developed to allow the pattern to flow seamlessly through the ribbing and the heel flap.

Not all pages will be needed for every size, so I advise checking the pattern and only printing the pages required.

Corcair was designed in memory of my dear mother-in-law. She was always interested in what sock (or other) pattern I was working on and was fascinated by the fact that I could design my own.
I worked part of this sample (in a shade of her favourite colour) while sitting by her hospital bedside.
