The sign for "happy" is made by placing one or both of your hands in front of you. Use "flat" hands, palms pointing back. Circle your hands forward, down, back, up, forward, down, back, up. Both hands move at the same time and in the same direction. On the upward swing the hands are very close to your chest or touch your chest. On the downward swing your hands are further away from your chest.
