There is a venue that I love, but they do not allow decorations to be attached to the walls or ceiling. Free-standing decorations only. Balloons are allowed but highly discouraged. Three of the walls are floor-to-ceiling windows with a gorgeous view. The back wall is just a plain white wall. I am thinking about some uplights, but I would love to include colorful paper lanterns! Maybe I could rent some coat stands, put helium balloons in the paper lanterns, then attach them to the coat stand so they float?
