Box The Gnat
Dancers step forward, join and then raise their right hands. The lady steps forward and does a left-face U turn back under the raised joined hands, as the man walks forward and around the lady while doing a right-face U turn back.
Dancers end facing each other, each in the other's starting position.

Facing dancers (man and lady).

4 steps from point of contact.

Start with a handshake position. The joined fingers must be held so that the man's fingers may turn over the lady's fingers easily while still providing some degree of security or stabilization. At the completion of the movement, the hands should be in handshake position.

Note: You should be facing the person you boxed the gnat with. Many dancers mistakenly think they should be angled. Face to Face.
