Before you do anything, rearrange your dorm room furniture. Here, the previous arrangement blocked the windows and didn't provide as much floor space. We moved the dressers and wardrobes against the walls to bring in as much natural light as possible.
I found an easy and quick way to decorate my college dorm door! I just used an old book for the paper, but you can use all kinds of colors if you want to. (But in circles for bubbles!) Cute idea for any door really!
