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.
