You can download the pattern for free on Ravelry: INSULATE! mittens
I used the same yarn as for my INSULATE! hat, which is '8ply Pure Wool Naturals' from Little Wool Company, in the shades 'Papa' (a greyish brown) and 'Pumice' (oatmeal). I still have over half of each 200g ball left, even after making a hat and a pair of mittens. This yarn is great for colourwork - it's fuzzy enough that the strands on the wrong side felt down slightly with wear, and its 2ply structure helps with stitch definition.
The thumbs are knit plain, with the Dalek's 'weapons' (the famous egg-beater and plunger) completed afterwards in duplicate stitch. Doing stranded colourwork in such a small circumference would be fiddly, so duplicate stitch to the rescue! For an extra touch of whimsy, I added a little heart above each 'weapon' - they could be omitted or replaced with laser beams if you prefer your Daleks evil.

The best thing about my new mittens? Epic Dalek battles... teehee... ;)
