Kathryn Vercillo

Corner-to-corner crochet (often just called C2C crochet) is a terrific technique to add to your wheelhouse. With C2C crochet, you begin in the corner of a crochet project, typically a crochet blanket or afghan square, and work towards the other corner in a way that produces a finished project that looks like a textured, layered version of the classic granny square. It is a unique technique with an original look but it builds upon basic crochet skills, which makes it is surprisingly easy to learn. This guide shows you how to learn corner to corner crochet and showcases some of the best C2C crochet patterns for practicing the technique.
