I like to create an elegant yet comfortable dining room settings. I have a curier with displays, that will stay. The six chairs will be side chairs and I need two arm or no-arm chairs at each end. My idea of the rug is 9'x12' since the room is 12'x15'. I am not sure if the rug color is to match the light gray wall or to match the chairs. The table is maghogny color.

A statement art piece above the fireplace would be a natural focal point. Try picking at least one color from the artwork and repeating it in details around the room. Also resist the urge to choose an art piece that lines up with mantel edges. Use a piece that is narrower or wider to ensure that the artwork is a feature and not just an extension of the fireplace.

Do what is ever appropriate for the style of your home. If you do have them, make sure they are sized, constructed, and positioned as if they are there to support the roof. Some suggestions:

Thanks @Beverly for the visuals! It definitely helps to see the potential for the room. Ironically, I saw a swatch of the rug before I ordered it and it seemed more beige even though it was described as "ivory." Thanks @Louise Smith for your suggestions. I'm not a fan of bright color rugs but I realize that others may have different tastes, especially on a forum like this. I'm planning on getting a 9x12 wool rug though, so not necessarily an inexpensive purchase. I'd like something that will last and would rather make changes with smaller accent pieces over time.
