So, funny story. This cozy started life as a fingerless glove, using the pattern found here: http://ohmystars.net/craft/knitting/pgloves.html
But silly me, I used a 4.5 mm needle instead of a 3.5 mm needle and thought everything would turn out ok because I have large (read: fat) wrists. It turned out way too big for me, so I reconsidered, modified, and turned it into a cozy for my teacup instead.
The bonus is that I've been planning to make a teacup cozy for a while now, ever since I started drinking peppermint tea (it's supposed to calm an upset stomach). So at least I got that out of my mistake!
With a lovely view of the hole where the handle goes:
A full frontal view (the white flecks are from the cup's design peeking through. It's a Goofy cup).
Brewing a cup of Stash Premium Peppermint tea (I only drink herbal teas because they're not made from real tea leaves. I actually don't like the taste of tea!)
Once my fingers recover from their knitting cramp, I'll try the fingerless gloves again!
