Old ugly church, need simple but effective decorations!

Hey Kara! Welcome to the community! The previous comment gave some great ideas. In an effort to hide certain walls or make a room look different, I've seen people put up drapes and lights! This can easily brighten up the space and you won't necessarily have to hang something up if the ceilings are too high. Have you thought about hiring a decorator to help you?

No worries! YouTube and Google will be your best friend! Most of the time draping like this is help up with pipes that are put together to make a frame like structure. It's not too hard from what I have seen but will take a little time and effort! You can also hang the lights from the top of the pipe, especially if they are battery operated!
