These mittens were made during the coldest time of the winter, which means too late. I was hoping to take some nice snowy pictures of them, but it's raining instead.
The main stitch pattern is from the recently published book of Estonian mittens from the collections of Estonian National Museum. There are more than 300 examples of old mittens in the book, accompanied by colourwork patterns (stitch patterns only, no full instructions).
Mittens with this particular pattern found their way into the museum in 1920.
These thumbs are not traditional, but have a gusset like fingered gloves. I think they are more comfortable and easier to make. I wanted to use these yarns, although the brown and dark grey stripes should have more contrast. Colours from the wider stripes in just a slightly lighter shade would probably work best for this pattern.
This kind of zigzag wrist section is also quite traditional and widely used. The mittens are incredibly warm because of the stranded colourwork. Don't think I've had a pair since childhood, had completely forgotten about that. Next winter, used they will be.
