Wargaming is a life-long hobby (at least in my case) and there are often things that we've planned to do at some point but have never managed to get around to, until much later.
as recently as 2015, I realised I could use one of them as the basis of my long-planned barn bridge. Construction (in approximately 20mm scale) comprised a basic internal sheet-polystyrene structure with cardboard roof and walls. To
the walls I glued matches and on the roof I put cut sections of those
wooden stirrers you get in coffee shops these days (presumably because the
public can't be trusted with teaspoons).
