I just bought this super cute coffee cozy off of etsy.com waysideviolet makes a bunch of different ones. I think they're a great idea if you are an avid coffee drinker like myself. I use a coffee sleeve every day in the fall and winter on my daily, sometimes more than daily, starbucks trips around campus. I could save a lot of paper this way. I bought a pink one too to save for someone as a gift.
