How to do a Quarter Thru (Right Hand Boxes) square dance step

Starting Square Dance Formation: Any Appropriate 4-dancer Formation (e.g., right-hand box circulate, left-hand facing diamonds)

TIMING: --6

Quarter Thru Formations Definition: Those who can Cast Off by the Right, then those who can Trade by the Left. There must be dancers who can do each part--the call is not legal from say,a right-hand tidal wave. If there are two side-by-side square dance formations each of which can do the call, dancers don't move from one to the other. From parallel columns, for example, each of the two box circulate formations does the call independently.
