Marquee letters can be setup many different ways. The best way is to hang them using nails, hooks, or string. They are not that heavy at all so you can even use some strong tape to fasten them down. Or you can simply lean them up against a wall. In this photo, the marquee letters are just sitting on top of the couch and leaning slightly against the wall. Its recommended to use a little tape to provide some extra support. The photo also shows 1 pin spot highlighting the flowers (setup on a table to the right) , and 1 Par 64 RGBA uplight sitting on the floor and tilted toward the couch to add a hint of color to the background.
