There are actually two possible cases to think about. First: what couples do when they
have progressed out of the set (and the answer is USUALLY "cross over and
wait"). Second: what pairs (not partners) do when they move out of the minor set at
some point during the sequence, like in "Cal and Irene".
In "Cal...", the end effects are pretty manageable and observe END EFFECT
DEFAULT RULE #1: Just face into the set (e.g., face up at the bottom) with the W on the
right, M on the left. It is very close to the way you shift out of the set. In this
dance, the default rule works for both cases mentioned in the first paragraph.
The DIAGONAL DANCE END EFFECT RULE: Dances that work out of the minor set with some sort
of diagonal action require that an idle pair station themselves on the correct side of the
set.
Some special cases worth mentioning: "Fiddleheads" by Ted Sannella is a great
dance and features an automatic crossover when you progress out at the ends. Other dances
require that an idle pair at the foot be on the 'wrong' side because the
progression happens everyone is on their non-home side. (I think "Be Here Now"
is one of those dances.)
Here's another one
Becket Formation
A1. Cir L 3/4, Sw N
A2. W Chain, 1/2 promenade
B1. Petronella bal & twirl, **** swing new N
B2. M almd L 1+1/2, Sw Partner
At the ****, the idle couple needs to be on the 'unusual' side for an idle couple.
This sort of thing is worth mentioning in the walk-through.
