Tea lights set in mason jars: I like this idea combined with frosted mason jars which is just a simple spray can. Place multiple jars at each table. We can get mason jars of all differing sizes at Goodwills in the area.
you can get the vases at Dollar Tree, 3 bags of rocks and the floating candles in a 6 pack at Hob Lob. With a super gorgeous orchid as the flower, in the colors of the wedding, you've got yourself a very pretty, and very thrifty centerpiece!
