A tea cosy is a knitted or fabric cover designed to keep a teapot warm for longer periods of time. It often features colorful and intricate patterns, providing both insulation and aesthetic appeal. The combination of "🍵" (representing tea) and "🧤" (symbolizing coziness) suggests a delightful and snug accessory that envelops your teapot, ensuring your tea stays piping hot while adding a touch of charm to your tea-drinking experience.
