Mason jars are not only cheap, easy to find but also give also a perfect vintage and rustic look for your wedding. Candles are also considered one of the cheapest wedding decorations, so why not combine both? Call out a jar donation from all of your family members or paying a visit to a flea market, you will get a huge supply of mason jar for pennies per each. You can put some sand into the jar before the candle but the combination of only candles and clear jars looks perfect already. You can have 3-4 candle jar centerpieces per table or create a big chain of jars if you have long tables at the reception venue.
