Oops! Well, actually not oops. This is quite common what comes to my hands when I am working with pattern making.
Especially when I am grading the patterns it begins to happen. Here I have been grading our Kuolajärven Lapinkylä siida's women's Sámi costume according to Kaisa Hyldemiina Mukkala's costume which has been is use and preserved despite of the discrimination and WW2.
At the moment I am working with baby luuhka and am at the point to grade it from size 62 to 98 cm. If you are interested about Forest Sámi clothing see the blog essay. It is in Finnish but perhaps you can allow Google to translate it and get something out of it.
