From parallel waves: All circulate once and a half. Those who were facing out are now situated at right angles to the wave in the center which consists of the dancers who were facing in in the original waves. The couples on the outside will arm turn half and then spread. The end dancers in the center wave move ahead to the end of a long line. The center two in the wave turn half and walk in a loop behind the nearest outside dancer and then step in between the outside dancers next to that nearest dancer. Finishes in a line of eight with couples alternately facing.
