Pick up the flattened dough by the edge closest so that your left hand is holding it with the thumb under the dough and the fingers on top and with your right hand hold it with the thumb on top and the side of the index finger underneath. Rotate and stretch the dough in a forward, circular, clockwise motion, slapping the far end on the table. Continue to rotate several times, until it becomes almost see-through. Then lift the dough at one point with two fingers in such a way that it drapes down like a piece of cloth and using a circular motion, spin the dough loosely into a snail-like round. Set aside on a greased surface.
