This mason jar centerpiece is easy-to-DIY for your wedding! Adding candlelight creates a romantic atmosphere and these mason jars will add both a rustic and whimsical touch. First, you’ll need mason jars (you can buy them in bulk here for about $1 each) and fill with water. Next, tie a decorative ribbon (or raffia, as shown below) to the top of the jar in a bow. Place a floating candle (preferably long burning) in each jar and group approximately 3-4 jars together on each table. Light each candle and enjoy!
