Evelyn writes about the sock in the book:

The lace pattern in these socks was inspired by a

collection of narrow embroidered flower ribbons. I always start by charting several motifs, and it was a happy surprise to see how the decreases curved the little lace flowers into ribbons of roses that could alternate with purl columns along the length of the socks. The simple rose rib pattern repeats over 7 stitches and 8 rounds, so it is easy to memorize. Once I decide on the lace pattern, I have fun planning a top border for the cuff that will flow seamlessly into the lace. However, the border in this project is optional if you would prefer to have uninterrupted lace panels running all the way to the top of the sock.
