Coffee cup cozy

I belong to the Whodunknit yahoo group (http://groups.yahoo.com/group/WhoDuKnit/) and am reading a book by Patricia Wentworth called Wicked Uncle. Since this group requires you to read a book and then knit an item associated with the book, I knit this: Reason bieng that the books are called cozies and this is a tea cozy, but since I don't drink tea, it's a coffee cozy!!
