This mobius scarf was made with two skeins of Homespun in Baroque worked in rows of double crochet a size K hook. It measures 52" in diameter and 13" tall and is worn wrapped twice. It is quite warm and perfect for a cold winter's day outside. It took me about three weeks of night crocheting to finish. The yarn colors worked out to be a striped pattern but that was a happy accident.
