This is a crazy window frame. Check out the old brick, in multiple layers. It looks very chic, but I'm not so sure its stable!

This pic is cheesey, but the orange curtain is great. Love the stripes and purposefully faded colors.
Matching pillow cases to window treatments can also help pull a room design together.
