A weaving move across the set. In a complete hey everyone crosses the set, turns around, and returns to where he started. If the hey is only "half way", stop when you are on the other side of the set. Like a set of railroad tracks, contra lines are made of three spaces consisting of two long lines separated by space in the middle. Even when everyone is in motion as in doing a hey, you are on one side, the other side, or in the middle. Cross completely across the set weaving left and right. Whatever shoulder you pass in the middle, loop in the other direction on the side.
