One cup - cozies

As desicribed at the begining of this blog. i sat down to design a tea cozy that is good for most sizes and shapes of cups (be it tea or coffee) and indeed they do work.
They have been tested by a large number of family and friends and all said that they really do keep the bevarage hot for a longer time.

The dimenssions:
21 cm wide (at the bottom)
20 cm long
Made of any sort of pre-treated fabric and is fitted with thermo isolation layer.
Decorated with all sorts of beads, ribbons, buttons, etc...

It also works the other way around and one can use it to keep a drink cold on a hot summer day
