Tea Cozies

When I make a pot of tea, I do not have a tea cozy to keep the pot warm.  So, I have been using a clean dish towel.  It is amazing to me that the dish towel helps to keep the tea pot and contents warm for a couple of hours. 

As I was looking on line, one sight made a distinction between a tea cozy which leaves the spout and handle uncovered, and a tea cover, which covers the entire pot.

Additionally, as I was searching for cozies, I came across a reference for koozie.  If you do not know, a koozie is a wrap for a can or bottle, usually a cold beverage.  Hmmm. Do you think it might be a variation on the word cozy?
