This is one of the best interpretations of a wedding arch that I've ever seen. Two trees (wish I had asked the florist the name! lesson learned) are simply tied together at the top, creating a beautiful, organic focal point for this ceremony on our oceanfront deck. The base/roots are covered, thankfully, otherwise it wouldn't work as well.
What a great idea. Just think about it, after the wedding, the couple could take the trees home, plant them, and enjoy them in their yard for years. Perfect re-purposing!
