The design of the Enigma Machine was ingenious. Based on a substitution cypher, it used rotating disks, a system of “plugboards”, and daily changing keys to keep—or attempt to keep—German secrets safe during both 20th century World Wars.
This toe-up sock has a fancy lace motif that reminds me of the Enigma disks. It has a gusseted, flap heel worked from the bottom up. Encode and Decode are fraternal twins - Encode uses the same lace but from the toe up, while Decode works from the cuff down. Work one of each to make a pair, and feel extra crafty!
