The Japanese kusudama (薬玉; lit. medicine ball) is a paper model that is usually (although not always) created by sewing multiple identical pyramidal units (usually stylized flowers folded from square paper) together through their points to form a spherical shape. Alternately the individual components may be glued together. (e.g. the kusudama in the lower photo is entirely glued, not threaded together) Occasionally, a tassel is attached to the bottom for decoration.
They are now typically used as decorations, or as gifts.
It is, however, still considered origami, although origami purists frown upon using its characteristic technique of threading or gluing the units together, while others recognize that early traditional Japanese origami often used both cutting (see thousand origami cranes or senbazuru) and pasting, and respect kusudama as an ingenious traditional paper folding craft in the origami family.
