Followers natural opposite. Followers natural opposite. This is your open basic. Repeat as many times as you like. Followers just do back basic here.
Followers now turn here as well, using the footwork in the last bullet.
Now the next bit is the same as the first for the leaders, and now the followers turn as the last bullet. This continues as long as you want, to get out, leaders just stop turning, go back to open basic. Back to closed basic. Remember when you're turning you're always facing the same side of the room.
