Place a small piece of tape on the back edge of the scene setter every 1 to 2 feet.
Position the scene setter on the wall the way you wish to hang it. Ask a friend to help as the scene setter can be large and cumbersome. Put the scene setter up at least a week before the event you are hanging it for, if possible, so there is more time to get the wrinkles out.
Attach the scene setter to the wall by attaching a poster tack or a thumbtack through every piece of tape. Stretch it taught between the mounting points so that it hangs as flat against the wall as possible.
Take the scene setter down by removing the thumbtacks or poster tack from it after the event has passed. Roll it around the outside of a cardboard wrapping paper tube. Place the tube inside a poster tube so that the scene setter is sandwiched between both tubes. This will prevent new wrinkles from forming in the scene setter.
