From Facing Couples (or a R-H Wave).
Pass Thru and Half Sashay.
Ends in Back-to-Back Couples.
Notes:
-
Remember that the Belle slides in front of the Beau
for a Half Sashay.
-
Try to blend the Pass Thru and Half Sashay
into one smooth movement. Anticipate the Half Sashay so that
immediately after you pass right-shoulders for the Pass Thru,
start sliding towards each other for the Half Sashay.
-
Remain facing the same wall throughout the entire call. Do not turn.
-
