From an Eight Chain Thru (or Parallel R-H Waves).
Right Pull By; outsides Courtesy Turn and Roll as Centers L-H Star 1/2 to end in Parallel R-H Waves.
The L-H Star 1/2 can be danced as 1/4 Right and Box Circulate twice.
If the caller says Star 3/4, then do another Box Circulate.
Thinking of the call in this manner makes it easier to
dance the call Phantom, especially if the caller modifies the amount
to turn the Star.
Cross Chain & Roll is the same as
Cross Chain Thru
followed by 1/4 Left.
$B1~MQ(B: Star 3/4, Star one full turn.
In both cases, the ending formation is Parallel R-H Waves.
Single Cross Chain & Roll [C4]:
From a Single Eight Chain Thru (or R-H Mini-Wave Box). Right Pull By; Centers Single L-H Star 1/2
(Left Touch 1/4) as Ends Single Courtesy Turn (Left-face U-Turn Back) & Roll.
