From a line of four or two-faced line: Do a half wheel across (or half a couples trade). Finishes in a two-faced line at right angles to original line.
BACKGROUND NOTE: The "Couples Hinge" was extracted from a longer movement by Ron called Couples Hinge And Trade (on the Challenge Dancing's Basic Calls list). From a two-faced line, the Couples Hinge movement is actually a fractionated version of older movements called "Four in Line You Travel" and "Weathervane."
