Something in the style of the legs of the chairs, perhaps?

I myself would see if there would be anything else out of the serie of the table, that I would like. For instance a display case, or two bookcases? I would rather go vertical on that wall. Put some china and crystal in it. Done.

Something antique is supposed to not be out of the same series, so you also shop for that.

Small question: why is the chandelier hanging at such a peculiar place? You are going to move it to the middle of the table, right? Although with such a long table it might be insufficient. The picture underneath has several lights, which I would prefer.

This long table could use a nice table runner in my perception. And I don't say that readily. Like this:

That chandelier that is not centered over the table is turning me off - can't think about anything else.!

I think a painted piece in the colour of the trim or, if you want to add an accent colour, an earthy green or blue would look beautiful.

agree,,,,flag it! he does it all the time.
