The pattern is KnitterGirl39's Midnight Sky Mitts, and I'm using Felici Sport in "Ecology" and Stroll Sport in "Fedora," held together.
I finished one pair of mitts using Knittergirl39's pattern. I made them out of Classic Elite Yarns Fresco (60% wool, 30% baby alpaca, 10% angora). I have enough yarn left over to make another pair of mitts.
I have also begun a pair of mitts usiing this pattern (but a shorter cuff) from the Skacel 20 Years of Trekking KAL. I am using the leftover yarn from making these mitts. They are made from Trekking 6 Ply tweed.
