Consider something from the same Granite Collection-- so the whites and grays will match and not clash. Something solid or a different pattern. Order a 2x3 as a sample.

You could also use a simple plain Jute rug....they go with everything.

Pretty rug. Why not just the same rug for the other room too? I've done that it my house.

Sorry but in my opinion no to the same rugs.

No rug in the Dining Room is also an option. Especially with crumbs and spills in the fibers. A bare floor looks nice and is easier to clean.
