A nice easy dance for introducing Contra Corners is "Down by the Riverside" by
Melanie Axel-Lute:

The dance is a progressive 3-face-3, ending with a basket swing in B2 after which dancer
open out with anyone in the middle, facing a new threesome. Like Erik Hoffman's
"Walpole Dollhouse",

you can think of it as a much simplified version of Pat Shaw's "Walpole
Cottage".
On account of the progression, dancers get to lead the contra corners figure with a
succession of different opposite active (center) dancers. Thus, dancers who don't
quite understand the figure are likely eventually to run into counterparts who can send
guide them in the correct direction. By contrast in a triplet, triple-minor, or
duple-minor setting, a confused dancer may be asked to lead contra corners with the same
equally-confused partner time after time.
