I'm having a great time sewing "One Leaf Tree" fingerless wrist warmers. The tree styles sell fast, so they are pretty much catch-as-you-can. I can occasionally take custom orders, so it's OK to ask. I use my wrist warmers every day. They are safe for driving because your fingers are bare, great for walking the dog, as well as indoor things like typing and sewing.
They can be pushed back to the wrist, with thumb nub tucked in, to free your hands, but still keep your wrists warm. Great for knitting and hand washing, or when you need to touch something wet and don't want to get your warmers all sog. Wash and dry with your clothes!
