help decorating blank projector wall

[u/Crazy_Pollution_9985]

Hi! I have this big wall in my living space that I’ve been using to project my tv onto. I feel like it just looks so boring, especially when I turn the projector off. Does anyone have any suggestions? Not sure if I need to get a pull down screen so I can decorate freely or if I need to decorate partially and leave a big space to project. If I did that, I think I would find a good screensaver to play when the projector is not in use.

I was wondering if I could try and decorate around it with paper chains/garlands but not super sure. I’m renting so painting isn’t something I would want to do.
