This knit hat is based on a knit cap worn as part of the US Navy uniforms in the 1940s, and is made using techniques including rib knitting, stepped ribbing, four-strand overlock stitching, and decreasing stitches.
Back in the 1940s, there were no factories that specialized in knitting hats, so hats were knitted together in factories that made gloves and jacket ribbing, and so they were knitted using the same process up to a certain point and then sewn together.
