An obvious place to begin is with color. One trick of the trade many designers use it to pull an accent color from the rug, window treatments, or upholstery to work into artwork on the walls. In this way, everything in the room is subtly unified, even if you're layering with lots of patterns or experimenting with several different hues at once. Try purple wall art that speaks to the sheer curtains on the windows; violet poppies make this warm shade sing, especially when the floral plaques themselves are placed on an opposite wall.
Metal wall art is elegant and classy, and it's a method of decorating your home that makes your decorations really stand out. It's an eye-catching accent to any room of any style. Go from classic and antique to postmodern abstract, and create a design theme that perfectly communicates your sense of aesthetics and style to visitors in your home. Choose metal pieces to add depth and texture to a room since most stand out from the wall to create a 3-D feel.
