Christmas lights, Pictures, and wall tapestries
Christmas lights and printed photos are a good way to decorate for cheap. Wall tapestries take up a lot of wall space, therefore making any room look bright and colorful.
Another very cheap DIY way to spice up your room is word art. Using any materials you have, cut out letters, hang them on your wall, and you've got yourself a very original wall decoration.
