Hi
Here is my pattern for the mug cozy.
Why use a mug cozy? Because it serves as a coaster as well as an insulator to help keep your cup of tea (or coffee) nice and warm. And what I really like about it is that you don't have to remember to place the mug on a coaster after each sip. Just slip the cup into the cozy and away you go.
