Two layers of knitting plus the airspace in between makes these very nice, toasty mittens and worth basically having to knit them twice!
These can be decorated or plain as you like. I like to embroider little flowers on the back of the hands for some people or you can just leave them plain on the outside and use spaced dyed yarn for the inner mitten so they appear staid and boring actually have a wild side when you get to know them better.
I’m not including embroidery instructions here as I’m not very good at it anyway, but I think there has been some discussion on this on the forums.
The basic logic to these mittens is this: you knit the inner mitten from a scrap or provisional cast on, then take out that cast on and pick up the cuff and knit the exact same mitten again, slightly larger this time. When both are done, you’ll have a lined mitten. Keep in mind that most of your end-weaving should be done before you complete the mitten as once you finish the outer mitten, you’ll have no access to the “wrong side” of your work and weaving in ends from the right side of your work can be awkward.
