In January, thousands of women all over the world marched in protest at Donald Trump’s inauguration wearing pink “pussy hats”. Now you can learn how to knit your own, in Geraldine Warner’s new book, Protest Knits, published last week by Herbert Press. Also included in the book are instructions for knitting anarchist socks, tree-hugger scarves and Nasty Woman mittens. “Knitting is a way for me to express how strongly I feel about the cultural climate, in the way that I know best,” says Warner, who works at an arts and crafts museum in East Sussex. “We talk about art as a place where we can hold difficult conversations and I feel the same about crafts as well.”
