Roll dough into a 16 by 10 inch rectangle. Shape each strip of dough into a circle, overlapping about 4 inches from each end and leaving ends free. Taking one end of the dough in each hand, twist at the point where the dough overlaps. Carefully lift each end across to the edge of the circle opposite it.
Tuck ends under to seal.
