This spiral afghan is made in Tunisian crochet in knit style. It features a spiral with increasing band width, like a shell. Note that one ball of yarn had a different pattern of variegation and led to a bold look to one arc. This afghan works well as a sofa throw or sit-upon because it is thick and heavy.
