During World War 2, knitting became known as a home front weapon of war. Literally millions of women, children, and even men, in Allied countries, picked up their needles. The craft provided an outlet for the grief and uncertainty of war, and a tangible way to help soldiers (from all branches of service) fighting overseas by knitting sweaters, blankets, headgear, and socks. Knit your bit became the rallying cry. According to the Canadian War Museum, an estimated 750,000 Canadian women knit more than 50 million garments.
