The Penrose staircase is a so-called “impossible figure” discovered by the British mathematician Lionel Penrose.

The socks are knitted from bottom up, with gusset and heel flap. They start with a clever cast-on. The bind-off forms an elastic edge.

To show best the staircase pattern, I recommend a light, solid yarn.

Penrose is a collaboration with Cuckoo Yarns.
