Winnow has panels of wheat heads traveling up the front and back of the sock and airy lace fans along the sides. I liked the fan stitch pattern as-is, so all of the sizing is accomplished in the wheat panels.
Feel free to vary the length of the leg to suit your taste as well as the yarn available. The pattern repeat for the leg is 16 rounds, but the leg can be lengthened or shortened in 4-round increments.
