This is a difficult question because it all depends on personal taste. I would recommend finding inspiration photos from Pottery Barn, Restoration Hardware, etc. Check out www.houzz.com for inspiration as well. I personally would choose chocolate brown, black, and taupe with an accent color. I love slate blue for an accent color with brown/black/taupe (like a silvery blue-gray). This is what I've done in my current house and I love the way it looks. A friend used the same granite as you with similar floors. Her furniture was brown and black. Her area rugs were black/taupe/cream. Family photos had black frames on the walls. Then her accent color was red (red pillows, art with red in it, etc). It looked very pretty. HTH, Good luck!

Karen, Rug should be arriving next week. I ordered a swatch of the fabric and it's looks perfect! Problem is the Fabric.com doesnt have enough yards in stock. Fabric Guru does but I was sure if the fabric would/should look the same even though it's from different retailers. I ordered the curtains for the dining room you suggested nd they 1000x better than any other ones I've tried (thank you for that awesome pick!). I've decided to paint the dining room so that it blends better with the rest of the house. Also currently looking for a light fixture for the dining room.

my daughter has similar chair and grey sectional...she has windows just like yours! She did a navy and white wide horizontal stripe. She got them on sale at Target I think, 5 panels and they are the shorter length and she hung them on a one inch diameter rod and they stop right at the bottom of the window, the rod is between the ceiling and the window top and are about 5 inches beyond the windows on each end...they look so cool and since they are not hitting the floor they hang nice and straight.......the sofa is in front of the window too,

Thanks Beverly. My calculus teacher used to say that "you can't tell the riders from the horses without pictures" - in this case scaled drawings. I don't have the room layout drawn to scale, so here's a couple of pictures that may help. Looking into room from behind columns. Room is approximately 21' x 17' (window wall to columns) Tape indicates about where a 12 x 15 rug would land - about 2-1/2' from wall Opposite diagonal corner with tape showing where the 12x15 would end up. It's about 28" from column. While this room is slightly larger (and elegant!), and doesn't need the pathway for the Master BR, the relative positions of the furniture is my goal. Note the sofa table and chair behind the sofa, but not on the rug - I would like to have a table and chair and don't care if they're on the rug or not. My preference is to have all the furniture on the rug. Is that enough info to help determine an appropriate size? I can try to draw out a room layout with walls and dimensions, just ran out of day today.
