Centerpieces can get really expensive. Ikea has a ton of inexpensive plants, vases, and lanterns (which we used) that you can use for centerpieces and resell or use for home décor later on. * I bought my pillar candles at Kirkland Home. They were the cheapest I could find and I searched high and low, let me tell you. The cheapest votives I could find were at Hobby Lobby.
Okay so it's just a store, but they had a great selection of rice paper shades that helped set the tone for our reception. We hung various sizes from the ceiling and attached satin ribbon that matched the wedding colors. It added an elegant touch and was a low-cost enhancement to our great reception facility.
