Not to toot my own horn or anything, but I made the Origami Peace Crane Mobile below. It was hung above the aisle I walked down at my wedding. Hours of folding colourful paper and beading string, but well worth it.
I got the idea from reading about how it is a Japanese tradition for an engaged couple to fold 1,000 peace cranes to be displayed at their wedding. This shows the couple works well as a team and will have an everlasting marriage. Wikipedia also has this to say about Peace Cranes:
An ancient Japanese legend promises that anyone who folds a thousand origami cranes will be granted a wish by a crane, such as long life or recovery from illness or injury. The crane in Japan is one of the mystical or holy creatures (others include the dragon and the tortoise), and is said to live for a thousand years.
I may not have folded a thousand, but I did fold several hundred. I think that is a suitable amount of time for peace and prosperity for us.
Too bad I need to find a home for it before I go.
