What is a tea cozy?

A tea cozy is a cloth covering for a teapot, used to keep the tea warm for a longer period of time. It typically has a padded lining to insulate the teapot and help maintain the temperature. Tea cozies come in a variety of sizes, shapes, and designs, often reflecting different cultural or seasonal themes. They are commonly made from fabric such as cotton, wool, or felt, and can be machine-washable for easy cleaning. Tea cozies are a popular accessory for traditional tea sets and are commonly used in British tea culture.
