My reception space has a stage. We're not having a band, so I've been trying to think of a way to decorate the stage, in a modern contemporary way. My planner is considering draping the stage with fabric, but I want to come up with a less expensive alternative. We may put some lounge furniture or some of the dining tables on the floor of the stage, which will take care of that. The primary concern is how to decorate the back of the wall, which is concrete and not very attractive. I've looked through photos of previous events at the venue, and while some are creative and nice, there are not quite the modern look we're going for. Any suggestions?
