Hello spooks!
I'm organizing my second halloween party this year, and I'm looking for some advice. I live in an student apartment with white walls that I cannot paint or do anything even remotely permanent with, and they look super plain specially during Halloween. Last year we used that stretchable black spider web to cover up the walls which worked quite nicely, but it was rather arduous to take down in my boyfriend's opinion.

I'm still going to use the web this year too because hey, it does look good, but what I'm asking is do you have any recommendations for alternative options? Are there some wall stickers (tried googling that but didn't come up with anything good) that cover up a bigger space? Something that brings texture? Thank you!
//Oh and to add, we do have colored lights available in our living room but not in the rest of the apartment.
