Most interior design elements have a lot of straight lines and square corners. Contoured edges can take away the feeling of severity or stiffness in your home enviroment, although straight edges do make a room seem more organized and orderly. Consider shapes like circles, ovals, arcs, bows, ellipses and half moons. These softer shapes will add a sense of flexibility, grace, joyfulness and luxury. They also add a natural feel since many elements in nature have rounded edges.
Lots of elements in your home lend themselves to a curved surface, such as:
Tables, Chairs, Sofas and ottomans, Mirrors and other wall art, Rugs, Tile patterns, Even curved walls, vaulted ceilings and arched doorways.
