TWEED - A collection of knitting & crochet patterns with Tweed yarns. At Erika Knight Yarn Collection there are two marvelous Tweed yarns that are presented in this pattern book: Pure Tweed and Gossypium Cotton Tweed. While Pure Tweed brings you the joy of a classic rustic Aran weight Tweed yarn, Gossy Tweed (as we lovingly call it) translates the characteristics of a Tweed yarn into cotton. The patterns (both knitting and crochet!) are designed by four talented knitwear designers. They took inspiration from (botanical) gardens and plants.
