Will they look good on a Christmas tree?

It is well to remember In the movie they appear on a small tree along with all the Twelve Days of Christmas ornaments. They are 31/2 inches in wingspan, so fit into the palm of one's hand. While we hear of many people happy with them on their trees, there are some who feel they are too small to register. Probably hanging the pair close together adds to their visual impact. If it is a gift from a friend and included among one's tree ornaments, then each year when they are brought out the memory of the friend is revisited.
