Centers Star Fold Thru
Jay King - page 101
From parallel waves or two-faced lines: Centers Hinge, and in the new wave across the set, the ends fold to form a four hand star in the center of the set. The star turns about three quarters and the dancers move into center positions in the opposite line or wave. If dancers were facing out in the original line or wave, they face out in their new location. If they were originally facing in, they face in again. Waves finish in two-faced lines and vice versa.
