As of February 9, 2020, this pattern no longer appears to be available on Ravelry.

You can change up the size of the mittens by changing the gauge.
I read about the thumb trick in Elizabeth Zimmerman’s books. Specifically in Knitting Around but I’m sure it’s repeated in her other books. She is a genius!
I’ve included a fingerless version in the same pattern so you’ll have two patterns for the price of one! Who doesn’t love a
bargain?
