In order to make my room feel a little more like a home and less like a jail (or dorm), I try to fill my walls with some color and personal items. Because dorms often have strict rules about paint, hanging things on the walls/ceilings, and just about everything else that makes a room feel like home, decorating takes a bit more creativity.
This year I bought handmade prints from Etsy to liven up my walls and create a focal point above my bed.

I like to make sure that all of the things I buy to decorate my room can be used when I move out (that lava lamp might seem really cool today, but I doubt I would want that when I'm in my first real apartment). I also choose items that can be easily repurposed or recycled when I am done with them. These prints are recyclable when their life is over, but they will also transition well into the real world with me after graduation.
