Wall art can do some pretty impressive things in a small space. It can anchor the furniture groupings, provide color and texture, conceal flaws in the walls, draw attention away from unattractive elements, and put your personality and style out there for everyone to see. Adhesive wall hanging products will allow you to outfit your studio apartment with wall art without marring the pristine drywall -- or requiring you to pick up a hammer. If you can't afford large, framed prints, construct a wall collage made up of small prints, wall sculptures, and even architectural elements. This is an option you can implement inexpensively and rearrange on the fly. If you're just learning to decorate, it's an easy way to change the look of your room in less than an hour.
