Noddy, if you're going to start making tea in a pot then you'll want a tea cozy (unless you like cold tea -- I do). If you knit or know someone who does have them knit you a "tuque" for your teapot -- a slit on one side for the spout, a slit on the other for the handle, and a pom pom on top to make you smile
(You'll love your brown betty; mine must be 30 years old and it's still my teapot of choice. Just rinse it with scalding water after use and drain to dry.)
