The immensely popular knitalong—an organized event where people knit together for a common goal—has only grown with the explosion of the Internet. Yesterday’s wartime Red Cross sock drives have evolved into today’s meet-ups at locales as diverse as cafes, state fairs, and major league ballparks, as well as international online gatherings; in fact, at any given time tens of thousands of people worldwide are involved in knitalongs, organized around a particular yarn, a favorite social cause, an intriguing project, a special event, or myriad other themes. Authors Larissa Brown and Martin John Brown present an inspiring look at centuries of people knitting together, and why knitters find the interaction so meaningful and worthwhile. Along the way, they offer 20 projects especially suited for different types of knitalongs.
