Non-hanging decor inspiration?

Our wedding venue is a historic building and doesn't allow hanging decorations on walls, windows, etc. I'm trying to come up with some fun decor ideas for the space, but all the decor inspiration I can find is stuff that our venue won't allow. In addition, the space is fairly small, and will need all of it for tables and dance floor, so anything that requires a large area is also out.

Did any of you have to get creative with decorating historic venues? What solutions have you come up with?

Our theme is basically just "looks like it could be a Wes Anderson movie", if that helps.
