Several variations in starting formation, but typically one couple facing another across the set, ladies on the gents' right. Ladies start first, followed almost immediately by the gents. From where you are, walk across to the other side of the set, make a nice loop when you get there and walk back to the side where you started. You end up in exactly the same spot you started from. The fun part is that everybody does this at the same time, crossing paths in a weaving motion.
All couples face down the hall, away from the music.
Twos step apart from each other and ones step in-between the twos. Sixteen beats to walk down, turn around and come back up. That way everybody has someone to smile at as they turn. Two couples facing each other across the set, ladies on the gents' right. Ladies extend right hands to each other, pull by each other, and give their left hand to the gent who is waiting for them on the other side of the set.
