The easy knot stitch on this sock is the same as the one that appears in my Brookline cardigan, published in the Spring/Summer 2012 issue of the online magazine, Twist Collective. Since the knots, which are worked at a tighter gauge than in the sweater, might be uncomfortable inside footwear, I chose to limit the pattern to the part of the foot that typically peeks out of a shoe. The instep decreases, instead of moving in the usual downward diagonal line, go in the opposite direction to meet at a point on the top of the foot. The heels needed a bit of reinforcement because the yarn I used doesn’t have any nylon; I thought that the “eye of the partridge” stitch looked more delicate than the standard heel flap slip stitch which creates vertical ridges.
