Style Secret: Curved LinesSouthwestern decor goes easy on harsh angles in favor of gentle curves. Arched door openings, rounded corner fireplaces and sloping walls give Southwestern spaces a sense of softness and fluidity. Even corners, such as those on this kitchen range hood, are blunted and honed down. But remember ... Curvy doesn't mean swirly. Rounded elements have strong profiles and unbroken lines rather than intricate curlicues and undulating swoops. The one exception? Scrolled metalwork, which works nicely with the aesthetic.
