Add More Shelves
You may think you couldn't possibly squeeze more shelves into your small space, but you'd be surprised. For example, you can lose your bed's headboard and create one out of a couple of shallow shelves that will easily hold books, magazines and your alarm clock. No floor space for a bedside table? Hang a single shelf next to your bed instead. Have shelves with empty space above them? Take them up to the ceiling. Going vertical will create so much more space than you ever thought you'd have. Add some crown molding for a built-in look giving it a decorative touch.
