Lighting the dining room seems to have been my recent obsession. I added a light to the wood paneling (opposite the wall of photographs) to mainly light up the space but also to shed some light on a fabulous painting that I recently purchased on eBay.
Here's a close up of the painting:
The light is the Beryll wall spot light from Ikea (which cost only $14.99). It comes with a really long white cord which is perfect for lighting pictures and blends in to the white woodwork. I used wire clips to secure the wire behind the painting and along the bottom of the molding so that there weren't an unsightly tangle of extra cord on the floor.
