Froebel star
A Froebel star (German: Fröbelstern) is a Christmas decoration made of paper, common in Germany. In English it does not have a commonly recognised name; it can be referred to as an Advent star, Danish star, German star, Nordic star, Pennsylvanian star, Polish star, Swedish star, Christmas star, or Froebel star. It is also sometimes called a Moravian star, though the Moravian star is a general category of geometrical shapes and the sixteen tipped piece of origami is specifically called the Froebel star.
