Historically, temari were constructed from the remnants of old kimonos. Pieces of silk fabric would be wadded up to form a ball, and then the wad would be wrapped with strips of fabric. As time passed, traditional temari became an art, with the functional stitching becoming more decorative and detailed, until the balls displayed intricate embroidery. With the introduction of rubber to Japan, the balls went from play toys to art objects, although mothers still make them for their children. Temari became an art and craft of the Japanese upper class and aristocracy, and noble women competed in creating increasingly beautiful and intricate objects.
