Free corner to corner crochet patterns, usually shortened to C2C. The fabric is built diagonally from one corner in small blocks, increasing to the widest point and then decreasing back down to the opposite corner.
C2C is how most picture blankets and graphgans are made. Because every block is one pixel, you can follow a colour chart square by square and produce detailed images that would be very difficult in ordinary rows.
It is far easier than it looks. There are only two things to learn, the increase row and the decrease row, and everything after that is repetition. New to it? Read the beginner guides first, then browse blanket patterns.
