I recently finished these very warm, 100% Peruvian highland wool wrist warmers. They are made with a bulky yarn and are very nice and toasty. And don't fret, if you live in a climate where it's still a little too cold right now, you can layer them over some gloves until it warms up for you.
I am very pleased with the colour - they are not just a regular 'navy' blue - they are more of a deep indigo, similar to the colour of brand new dark jeans.
If you are interested in them, they are currently in my shop:
