If you want to inject a little life into a space one of the best ways to do so is by adding some patterns. A pattern is a decorative design consisting of a shape (or shapes) set against backgrounds or other shapes. Patterns come in unending varieties of designs, shapes and colors.
It can be done in a small way by adding a patterned accent pillow to a chair or sofa, or framing a piece of patterned fabric and hanging it on the wall; or it can be done on a grand scale by wallpapering an entire room or covering large furniture with patterned upholstery. It all depends on what kind of look you're going for and what suits your style.
The following articles will help you figure out what patterns will work best for your space and how to mix and match patterns to achieve a desired look.
