What is corner-to-corner crochet (C2C)?

Corner-to-corner crochet (also called C2C) is a technique where you crochet diagonally instead of in rows. The project is built using small blocks made of chains and double crochet stitches, starting in one corner and growing row by row until you reach the widest point, then decreasing to finish the opposite corner.

C2C is especially popular for crochet blankets because it works up quickly and makes color changes easy—perfect for graphic designs like this brontosaurus crochet blanket.

Why you’ll love this pattern
