I always start with the quality of the tablecloth and then everything else follows.
Damask is a favourable cloth because it demands less on the table and it can give you more options for your chaircovers if you opt to dress the whole table. Otherwise, tiffany chairs can do the trick.
Most important, give attention to your centrepiece. For a great evening for your guests, place a low flower arrangement or centrepiece with a glass mirror. You will never go wrong with less is more and your guests will marvel at the setting.
