NEW YORK—The American Museum of Natural History opened its annual display of the Origami Holiday Tree on Monday. The tree features more than 500 decorations, which volunteers began folding in July. This year’s decorations are in the shape of some of the “largest and most impressive animals and inanimate objects found in the museum halls.” Volunteers will be on hand to teach visitors the art of origami while the tree is on display until Jan. 2.
