A mug "cozy" pattern I found online!  So cute, super simple to crochet, would make excellent Christmas gifts/ stocking stuffers.  Took me about 1 1/2 hrs to make, but that was learning some new techniques & everything from YouTube.  Link below:

Taken from blog: crochet n play designs blog. (Tweaked mine a bit to fit this particular type of mug, which was a graduated design.  I recommend having the cup in hand when you're crocheting, stopping to fit the piece around the mug from time to time to make it a custom fit.)

Have fun with it, change colors, or add animal faces and features such as the classic sock monkey design!
