What should i do with an empty

[tanviralikhan]

I want to make my room more personal but I don't want anything permanent. I already have wall decals and a photo wall, I also wrote on my wall in chalk. The only wall that is empty is the wall against my bed. I don't want to do anything permanent but I want to personalize it, I wanted to put up road maps of places I've been and want to go but I don't know how to do that. Any ideas like that or better?
