“Typically in a longways set casting down a place; unless you are already facing out or down you turn up and out of the set (the long way round), and then move down the set past one person.
Common variations are to cast to the bottom of a set instead of just one place, or to cast left or right in circular sets. If a caller tells you to cast left one place he probably means turn to your left, but then move one place to your right, but there again he may mean move one place left. Use initiative!
Casts take four or eight steps depending. Slower dances give you a sweeping eight steps, faster ones don’t.”
