skip the towel rod. It's always hard to decorate around the towel rod. Plus, this fits a LOT more towels. I completely agree about skipping the towel rod.unless it's a heated towel rod in Michigan in winter :)
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!
