Your wood floors are absolutely BEAUTIFUL!!! You lucky duck! Now....in my humble opinion....here are a few suggestions... Your sofa works great as a room divider. But...pull 2 chairs in closer to the sofa, facing it. Put a coffee table in the middle, and a big rug, that goes under the sofa, coffee table, and 2 chairs. This will make your seating area cozier and more inviting. Your green lamps are okay, if you are trying to pull in some green. I would also bring some green into the curtains, maybe a painted cornice, or even green valance? Also, definitely green pillows on the couch, along with your other colors. Maybe some chenille throws, over the chairs? Your fireplace mantle maybe could use some "punch" of greenery, either with some pillar candles, or maybe some beatiful silk ivy? Do you have any kind of a table to use behind the sofa? That would really dress it up behind there, and be another place to add some "things". Dining are.....another big rug, to go under the table and chairs. Maybe a berber rug in a neutral color? That way it would be easy clean, and low pile? It would not have to match your other rugs in living area and hallway, as this is another room. As long as it did not clash terribly, it would be fine. Again, maybe some color on the window dressings? Maybe some fabric seat cushions? You have a wonderful room to work with! Possibilities are endless. Nice open, clean space. Go for it. Fill the rooms with things that are "YOU". Things that you love and cherish. Give it your own personality. Whatever style is best for you....contemporary, country, primitive, elegant.....you have the walls and flooring to do whatever is "YOU". I am sure it will turn out wonderfully! Just by restoring those wood floors....shows that you have TASTE! Good luck, and most of all, enjoy decorating. That's what it's all about. Creating a room (s) that we can be proud of, and then feel "at home" in, when we are all done. Carla
