We are working on yet another one shot larp which takes place in a modern institution where lots of weevil things happen. Anyhow, in order to scare the bejesus out of the patients during their morning walk, we want to create a mini graveyard where the deceased are only identified by their number (in the same way that the patients players will). We're looking at having 15+ markers, hence the need for something simple.
So I whipped this prototype. The top is birch plywood and the bottom is pink insulation foam and some screws and nuts i had laying around. Everything is covered in drylock for texture and to be weather proof and on the day of, I'll probably treat it with hydrofuge spray.
I made the top part float over the bottom part so we can run hidden fishing lines to anchor them to the ground. It would be a shame if the wind took away our graveyard.
