Knitting and the Vietnam War?! Really?! Yes! During the Vietnam War, 2 Canadian organizations Canadian Aid for Vietnamese Children (CAVC) and Voice of Women (VOW) used knitting as a way to help the Vietnamese people. Here are some of the links that I found so you can learn more about what happened.
By the end of its first year, VOW had 6000 members. It organized an International Women’s Conference in September 1962- the first meeting in Canada to include women from the Soviet Union and other socialist countries. Conference delegates called on the U.N. to designate a World Peace Year. The idea was taken up by Prime Minister Nehru at the UN, and 1965 was proclaimed International Cooperation Year.
VOW has organized unique activities to draw attention to its cause. In 1963, it collected and tested thousands of baby teeth from children across North America to demonstrate the fallout from the atmospheric testing of Strontium 90, a harmful radioactive isotope. During the Vietnam War, the Ontario VOW organized the Knitting Project for Vietnamese Children. Over a ten-year period, the group sent thousands of hand-knitted garments and other aid to the child victims of the war and their families.
Over time, VOW has expanded its focus to include human rights and civil liberties, preservation of the environment, as well as economic and political issues.

Presumably some of the young Canadian knitters and other youth volunteers found kinship with the unknown Vietnamese children they were assisting or when they imagined themselves in the same situation. Zoya Stevenson, a Toronto teen, participated in the CAVC knitting campaign because she could relate to the Vietnamese children affected by the war. “The napalm bombing of innocent women and children (like myself) shocked me,” she recalled, elaborating that “the fact that these acts of terror were sanctions by citizens of my own country, frightened me terribly.”
