Re-doing my room…

Re-doing my room…

Hi everyone! I've been watching this community for a while but haven't posted anything. I'm just moving back into my old room at my parent's house and moving out of a dorm (I live near my school) so I can save some money since board and food are wickedly expensive at my school. My room is on the second floor of an old house and I don't want to put any nails in the cieling, but I want to hang a mobile and play with space and things like that. Any advice on how to get things to stay up there without using nails? Thank you! I'll post photos of the new room soon <3
