In the living room, we purchased a dark gray sectional (that we absolutely love - now we can all fit on the couch at one time). We also painted the walls Montpelier Ashlar Gray. Still to come are curtains, a larger rug and I'm thinking that adding an arm chair or two on the left might bring the room together. I've also got my eye on a new tv stand to hide all of the wires and cable box.
It's definitely not quite "there" yet, but we're making progress towards our final vision for the space, which is exciting!
