Hang and twirl streamers to create a pretty picture backdrop. Would be cute for gender reveal parties, have one blue wall and one pink. Guests take pictures in front of the wall that corresponds with their guess.
My best friend growing up had one of these in her back yard (but it was part of the landscape with bushes enclosing it) we spent hours and hours building furniture and houses for the fairies out of anything we could find. The memories are magical. I hope I can do something like that for my kids some day.
