Something like this.
Where people stick their heads through for a funny photo.
I don't even know what these things are technically called. Face-in-the-hole? Carnival cutout? Face hole board?
I'm planning on using a plywood sheet for the face of it. This thing has to stand outdoors for several days, and withstand a certain amount of abuse and weather, so any options made of cardboard or foamboard are out of the question.
Painting the image is easy. Cutting out the holes for faces is no problem. But I need some advice or instructions or plans on how to build a proper support behind the board, so that it stands on its own and doesn't easily topple over and kill someone. Bonus points if the supports can fold down or detach for easier transport. Also, in addition to any lumber support, do I need sandbags or something else to weigh the whole thing down?
I have at my disposal a power drill, a jigsaw, a circular saw, all my fingers (for the time being), and half my wits. Thanks for any advice you can give!
