This pattern includes written instructions for creating this mosaic crochet design. The size can be adjusted by altering the weight of the yarn and size of the hook.

The technique is mosaic crochet overlay, where the colors alternate each row. You can hide the ends with a double border. You will be working on the same side of each row, so the front of the blanket is always facing you.

You will need approximately 2500 yards of the Alternating Color (white in the picture) and 400 yards each of the rainbow colors.
