A Kitchen Look We Love: Black + Marble In this kitchen from Traditional Home (via Savor Home), marble gets punched up with just a bit of black, in the window frame. Bonus points for the way the subway tile wraps into the deep window opening. That's a nice detail.
If you've got beautiful natural light streaming into a room or windows with extra architectural detail, then there's no reason to hide them behind curtains. Go au naturel by foregoing the curtains and other adornments, like Carter Kay did in the design of this Atlanta kitchen.
