Personally, I'm one of those people that doesn't see a table as just a table. There are so many different things you can be doing with your table to make it so much more entertaining. People by nature enjoy visually stimulating objects. If you place a white piece of canvas in front of a group of people and bring in a painting done by an artist - they are always going to gravitate towards the more colorful and stimulating object rather than the plain object. This is pretty much common sense.
I don't think people realize though that your table is the same way. You don't have to have it looking plain Jane. Add some flair! Add some color! Add some beautiful pieces and drink dispensers and you are going to have your guests talking for hours about the beautiful crystal wine or brandy decanter you have on the table. You are going to have people asking where you got the drink dispensers and how it looks like it costs a lot. You will be the talk of the town when just adding and adjusting a few simple things.
I know some of you are scared to replace anything you have now or to add too much color! If you are nervous you don't have to go crazy with colors. A couple of accent colors such as red, green, blue or pink are going to go a long way, especially if your tabletop accessories were limited to really dull colors! People are going to notice the small things as well! The point here is to go outside of your little box, but to also do what feels "comfortable" to you! It is your table after all!
Hey, if I had my choice I would add a crazy Jamaican theme just to see you squirm and realize in the end that it wasn't that bad (and kind of fun!). But this is your home, your table and your choice! However, if you would like to change a few of your tabletop accessories, you have a whole truck load of options to choose from. So go crazy, go classy, just go go go!
