Kate Atherley has been teaching knitting professionally for more than 15 years at stores and events all over Canada, the U.S., and the U.K. Custom Fit Hats is her ninth book, and the fourth in her series on customizing projects for perfect fit and style; it joins works on socks, mittens, and shawls. Her focus in all her work is the empowerment of knitters, illuminating both the methods and mechanics of the craft. The combination of her university degree in mathematics, professional experience in software development and usability, and training in garments and fashion design give her a unique perspective. She also works as a technical editor, helping other designers and authors bring their work into the world. She lives in Toronto with her husband and the family of skunks under their porch.
