Knot Socks–Making Progress

I’m making good progress on Nancy Bush’s Knot Socks (p.96 of Sock Knitting Master Class) and things are going smoothly. I’ve knitted the leg, heel, and gussets and I have to say that I love the yarn (Three Fates Tethys) and I love the simple rib and cable pattern.
Nancy used the Dutch heel for these socks. It’s been a long time since I’ve done this type of heel and I wonder why. The heel turn is done in such a way that the center heel flap stitches continue uninterrupted (in the heel flap stitch pattern) along the base of the heel. It makes for a well-fitting cushiony and durable heel.
