This is my dining room table set, except ours seats 10 and is huge! We have a formal dining room area that is huge, and we had to buy that table last year to fill the space.

How can I decorate the top/middle of it? I am horrible at design/decor, but the table is so huge and looks bare without something on it! Help a clueless girl out! I'm going to run out this evening and try to find something to put on it but could use ideas. TIA.
