I am getting married in July and having the reception in a church gym. It's nice but really big. The ceiling is really high and there are windows that are really high up as well. The colors I want to have are hot pink and emerald green. I love retro or vintage styles but have no idea how to work that into the gym decorations. Furthermore, I don't have any ideas on how to make the space more comfortable and less spacey. Also, I don't exactly have the biggest budget so any money saving ideas would be wonderful. Does anyone have any ideas?
