The mittens feature a triple square motif on the backs, and chevrons on the wrists.  They are pretty loose, so they work well as layering mittens over gloves or mitts.   I found them tricky to work, mostly because the ground changes from garter to reverse stockinette to stockinette under the cables, but my trusty sticky note on my chart helped me navigate.  I loved the visual integration of the chevrons, the proportions of the mittens, and the squares on the back of the hand.
