Hello there! I'm a newbie here and this is my first post and I have a question. I rent a room in a house full of college students, and sometimes the hall light wakes me up because it comes into my room through the cracks around the door. Does anyone have any suggestions on what to put around the door/doorframe to keep as much light out as possible? is there something I can buy at WalMart or do I have to make something myself? Thanks!
