C2C crochet stands for corner-to-corner crochet, which is a type of crochet pattern that is worked diagonally from one corner to the opposite corner. This technique is often used for making blankets and afghans, but it can also be used to make other items like scarves, shawls, and dishcloths. C2C graphs are grids that show which yarn colors to work in each tile, and each square in the chart represents one tile. The C2C technique works a little differently than standard crochet: as the name implies, you start at one corner and work back and forth in diagonal rows until you reach the opposite corner. Each diagonal row is made from several “tiles,” also called “squares” or “blocks,” and each tile is made from 3 double crochet stitches, plus their corresponding 3-ch turning chain. The C2C technique uses the same basic crochet stitches you might already know, such as chain stitches and double crochet stitches. C2C crochet patterns can be used to create words, characters, and graphic designs, and you can even learn how to design your own C2C patterns and translate a photo, illustration, or logo into a C2C graph.
