Tea cozies are misunderstood.
Often the butt of jokes. Relegated to the frivolous. Accused of the crimes of being useless or 'ruining/cooking' the tea. Tea cozies are the jester, the idiot uncle in the tea family.
BUT ... if you like good tea, then a tea cozy may be just the thing you need to make an even better cuppa'. I'd like to teach you how to use one properly - and perhaps - just perhaps - you will use a cozy to make an even better cup of tea than you are now. That idiot uncle might just be a genius!
