I thought this was a good example of a simple but easy centerpiece. A lot of weddings I go to that are DIY the centerpieces either look too bare or too contrived. This is perfect because it is low on the table so guests can talk to one another but because there are so many candles it makes a BIG impact. Jamali Gardens is a great resource for vases, candle holders and candles.
