The mittens are finished! They are still unblocked, but I couldn't wait to post about them. As it is somewhat warm round here, I'll have enough time to get them ready for the next cold days.
I did not follow any specific pattern for this one, just used some traditional motifs out of a Lithuanian booklet for mitten knitting. I learned how to do a Latvian braid here. This is a very easy and straightforward tutorial. Thumb construction was done according to this tutorial.
All other details are on my Rav project page here. I am very happy about how these turned out and am off to start a new pair.
