Design by Sarah Hauschka. A true Moebius strip has only one surface, and only one edge. Intriguing to knit, this geometric oddity makes a beautiful yet functional scarf. When placed around the neck, it crosses itself in front and stays in place. If looped again around the neck, it becomes a snug neck scarf and if you pull one edge up over your head it becomes a wimple. A soft lace or fingering weight yarn.
