Mason jars have become very popular in wedding decor lately.  But there are lots of ways to incorporate this vintage element into your wedding decor besides using them as containers for your floral arrangements (although they are great as containers!)  Here are some different ways I have found for you to use mason jars in decorating your wedding (or party, or home):

Top Row:  Drink jar by Sabine Scherer, jar with river rocks and candle by Kate Harrison, jar chandelier by Jamie Grenough via Style Me Pretty, hanging jars with florals by Jennifer Roper
Bottom Row:  Jar escort cards by Sean Walker, jelly jar drink by Ian Grant, lots of jars and candles via 100 Layer Cake, floating candle in jar by Jennifer Roper

I love the idea of using the jars as candle holders, either floating them in water or putting river rocks in the jar.  And how amazing is that mason jar chandelier!  I had to post another shot of it:
