WWI and WWII Knitted Hat
This hat pattern is accurate for both WWI (from comparing original patterns) and WWII (from original photographs).
This hat pattern is a reconstruction from a photograph held by the Commonwealth Air Training Plan Museum in Brandon Manitoba. The member of the ground crew is arming an aircraft wearing a 2x2 ribbed skull cap.
In his 1987 book, A History of Hand Knitting, author Richard Rutt states, “Knitting [for the allied]…armed forces in the Second World War could be done in three colours, for ‘Air Force Blue’ had been added to navy blue and army khaki.”
Knitting in WWII was very prominent on the home front. There are many surviving knitting patterns for “service” cardigans, vests, scarves, hats, gloves and more. During the war multiple yarn companies and other organizations from the Red Cross to the Salvation Army released patterns or pattern books under the slogan “Knit for Victory.”
This hat pattern is based off Beanie No. 212 from Bucilla Yarn Booklet, Volume 318, dated to 1940. I also took some adaptations from Helen Waittes’s interpretation, Classic World War II Watch Cap, also available on Ravelry.
