Expand your curtain rods to give a few inches beyond the window frame on either side. This will not only make windows appear bigger, it will also ensure that when you draw back the curtains, they don't block any light from getting in. In addition to maximizing window width, mounting the braces slightly above the window will give the illusion of height.
This is a great example of a transitional kitchen. Streamlined shapes, open shelving, and boxy lighting give it a modern look, while details like wicker stools, glazed subway tile, and a Persian rug lend it a more traditional air. The Carrara marble helps marry the two styles together.
