I finished a pair of Evangeline mittens a few weeks ago, and I'm super happy with them. I made them with some of the leftover Cascade 220 from my Circle Square hat, and even after these two projects I still have a small ball of yarn left. I made them with 5 cable repeats instead of 3 or 9, and I think they are just the right length. I made the thumb hole a little tight, trying to compensate for the overly-loose thumbhole that my fetching mitts have. I also picked up many more stitches around the thumbhole than the pattern called for, which makes the fabric around the thumb less holey and more insulating, like a mitten should be.
Fingerless mittens work great for me on weekday mornings when I'm rushing to the bus stop, knowing that I won't be spending much time outside and that I'll have to dig thru my purse for my bus pass.
I reversed the cables on the mitts, so they are mirror images of each other.
