It was by accident that I discovered this Goth fabric glows in the dark! Of course not for too long, and it needs light first, but still it is such fun. First choose the size cozy that is right for your teapot. You will find my size chart in the product photos for this listing. Need something else? I'll try to oblige. A collector of fine Japanese fabrics this is a gorgeous piece of new vintage cotton that has birds (I think they are seagulls) flying over reeds, light shining down abstractedly, with reference to winds and clouds as the sun fades in sunset. It is a haiku all in itself.
