From an Eight Chain Thru (or Parallel R-H Waves).
Right Pull By;
Outsides Courtesy Turn and Veer Left as the Centers
Step To A L-H Wave, Very Centers Left-face U-Turn Back (placing
R-H on adjacent End's back), Courtesy Turn and As Couples Extend.
Ends in Parallel R-H Two-Faced Lines.
The Courtesy Turn movement for the new Centers (after the R-H Pull
By) is sometimes described as 1/4 Out; Courtesy Turn & 1/4 more.
We dislike this definition for 2 reasons:
The original Outside Belle's part is somewhat awkward because
there is first a 1/4 Out (to the Right) and then Courtesy
Turn (to the Left) 3/4, instead of just a smooth 180° Courtesy Turn.
If you advance into C3, the caller may call a Left Chain The
Square in which case we believe it is easier to remember to have
the new Centers Step To A R-H Wave & then the Very
Centers always turn the Ends. If, instead, you were to 1/4
Out, you can easily become confused as to who turns who.
After the new Centers Step To A Wave, it is always the Centers of
the Wave that take the Ends back to where the Ends came from.
