There's something just fun about convertible or "flip-top" mittens. They have all the warmth of regular mittens, with the added practicality of being able to get to your fingers when you need them. This makes them ideal for situations where you want to stay nice and toasty warmsuch as in a snowball fightbut still need some manual dexteritysuch as when you need to open the door to run back inside! The pattern includes instructions for a child's size and three adult sizes, with modifications to make either a fingerless or "regular" set of mittens rather than convertible ones. These mittens were inspired by some lovely handspun purchased at the Mass Audubon's Drumlin Farm in Lincoln, MA. The wool will gradually felt slightly with use, adding even more to the waterproof and warm aspects of these mittens. Heavy worsted weight wool means the knitting on these flies by! Look for the "Jaume" ribbing motif repeated in a hat, cowl, and other Katherine Vaughan Designs patterns designed for men and their families.
