When Knitting was a Manly Art  is a 1997 Christian Science Monitor article, written by a man telling his experiences about knitting in boarding school during World War II. 

He writes that no one thought anything of boys/men knitting, and that everyone at school knitted, ” including the headmaster, the teachers, and the whole football team. We knitted 9-inch squares, which somebody else sewed together to make blankets and scarves for British soldiers. “Knitting for Britain,” it was called.”
