Bend the line: Keeping hand with neighbor, those on the ends of the set move forward four small steps while those in the middle of the set fall back four small steps, turning as a pair through 90 degrees, and ending in lines across the room.

Written in honor of the double celebration of Pat and Ken Moon's 50th Wedding Anniversary and of Ken's 80th birthday.
