From Charlie’s Aunt:
The style in this pattern is influenced by the caps popularised in the 1940s. I love the fact that it is a modest shape and construction is simple, but it is very versatile and stylish, making up equally well in cotton canvas or drill for a nautical look, or in corduroy or tweed for a country feel. It can be worn all year round and is offered in ONE SIZE (medium size 22.5” head approx.) with tips on making it smaller or larger.
