If you've ever seen AMNH's awesome origami-adorned holiday tree then you know the skilled folks over at OragamiUSA (the team behind the ornaments) are true experts. Try your hand at the art of paper folding while teachers from OrigamiUSA lead a family-friendly session where first-timers can craft easy ornaments, including stars and animals, for the holidays. Kids might even have a chance to fold a festive tree. Sessions are held in the School Lunchrooms on the lower level. Ages 8 and up.
