I'd go for the black : )

LOL, how 'bout black on one side and red on the other! Opinion's seem to be split!

My vote is for the black.

Black.

Very nice, I would choose the black binding for this one.

Black

Black - adds to a classy look

Red!

I, also, vote for the black. Keeps your eye on the table runner instead of the binding.

Red since the sashing is black

I would use the red for a cherrior affect and the black to look classier. I would choose the red.
