Christmas ornaments are typically made of various materials such as glass, plastic, or metal. They often feature intricate designs and decorative details, making them a popular choice for adorning Christmas trees. Some common types of ornaments include baubles, which are round, shiny spheres usually made of glass or plastic; tinsel, which is a thin, glittery strand of metal; and figurines, which are small, three-dimensional objects that represent various characters or symbols associated with Christmas. Additionally, some ornaments are made from natural materials like wood or clay, and some are handcrafted by skilled artisans.
