do it yourself
One page per kind of place — a square, a car park, a courtyard, a queue — for getting people who do not know each other into the same place and giving them something to do together.
Pick the kind of place you have. Each sheet says what it takes, what to do in what order, and shows it having worked somewhere else. Then tell us how it went, or do not, and do it anyway.
