The Hypnotic Spiral Sweater is worked by making two granny squares, sewing them together, and then working sleeves. It is suitable for beginners or anyone with basic crochet knowledge. It calls for two different colors of yarn, and you will need about 450 meters of each other. The size worked in the pattern is an oversized medium or standard large, but the pattern explains how to create any size sweater and is easily adapted for all.
