Inspired by the Bombe machine, used in the decryption process at Bletchley, the circle motif represents the drums on the machine. Worked in the round and grafted together to give a fully reversible cowl.

This pattern is part of The Bletchley Collection, a six piece collection for Eden Cottage Yarn’s Milburn range inspired by the WWII code breakers stationed at Bletchley Park.
