This design is one of the items in the Kaleidoscope Socks collection by Mary Dominski.

The design of these cuffs lets the colorful painted yarn peek out between ridges of the main color. They’re ideal for wearing with leggings or as slippers after a long day wearing business shoes. Let the main color carry the day (and use up the leftover painted yarn from one of your other Kaleidoscope Socks!)

Top-down construction.
