The center of the turn will be at the joined arms, so, while turning, each dancer is moving equally around the other. Thumb should overlap the back of the opposite dancer's hand. It is important in right and left grand to release hands when passing. Do NOT stretch or lean over to reach the next hand. Hands revolve around each other maintaining contact and a certain degree of security or stabilization.
Slight pressure is all that is required.
Thumbs are gently closed on the back of the opposing dancer's hand. As the turning action starts, wrists are straightened. Four men with palms down take the wrist of the man ahead and link up to form a box. Arms should be bent slightly so that the height of the handgrip will be at an average eye level. Dancers should stand erect and tall, shoulders back.
