Well, I ask you, what is more disappointing in this world than a tepid cup of tea?! Ok, so maybe you could give me a short list, but I think you'll agree that a nice hot cup of tea is something rather special. At a time when more and more people are turning back to leaf tea made in a teapot, I think it's a good time to reintroduce the good old tea cosy. They may have a bit of a reputation for being dated, but I will defend them up to the hilt. They genuinely keep your tea warm, and that in turn saves you from having to keep getting up to reboil the kettle.
There! Have I sold it to you?? Tea cosies are back!!
The large ones will go over a decent sized pot, as well as a small pot and cup. And the small ones are designed especially to go over a two-cup pot, or just the cup while you wait for the tea to brew.
