Here's the photo of the March socks from Katherine Pence's A Time to Knit Stockings.
I'm making mine shorter and I'm going to continue the cable pattern down the back of a Dutch heel. I'm probably also going to continue the main cable all the way to the toe.
Working on this sock has made me fall in love with this booklet all over again. It is out of print but the designer (now Katherine Misegades) is working on a reprint - info HERE. Here are three of the patterns from the booklet I knit years ago.
