Much like art in a broader sense, interior design is important for several reasons that can be overlooked in typical societal value assessments. Consider this blog post my ode to interior design as an enjoyable and, I daresay, necessary form of expression.
The art you keep in your home is often the finishing touch that most transforms a space from "a room" to "your room." You can select the most beautiful furniture, the trendiest textiles, and so on, but the art on your walls is a direct reflection of your passions and personality. The easiest way to shop for art is to set some parameters for your search before you even start. The more specific your search, the more likely you are to find the piece that is calling out to be added to your space.
