Chain stitch, [stem stitch?] slab stitch, running stitch, fringe. This looks like it belongs to an old embroidery tradition that was once widespread but has only survived in a few places, showing some similarity to the embroidery of Horodok, Yavoriw, Bilgorai, Kurpie, and even the old Lowicz embroidery. I may mention here that at least some archaeologists believe that west Ukraine/southeast Poland was the original homeland of the Slavs, certainly there have been Slavic settlements in the area for a very long time. The other two drawings she published do not really fit into the same style, being very free form floral interepretations of chainstitch. These also remind me of Tatar work.
I have some imput from a reader, Vasyl, who sent me an actual photograph of what i believe is the very same piece of embroidery from this region. You can see that it is mostly free-form satin stitch. The green seems to have faded.
The image at the head of the article is of the same piece.
There are examples of uncounted floral embroidery in western Ukraine, but they are based on satin stitch and stem stitch. This is unique in Ukrainian embroidery, as far as i know.
Here is Kul'chytska's sketch of the man's costume which has recently become available.
Recently more of her sketches have become available. Here is another one.
Buttonhole stitch, back stitch, running stitch, slab stitch, and she seems to indicate in the bottom sketch that the zigzags are chain stitch. Here is another, newly available sketch.
Here are photographs of the actual museum pieces.
This again seems to have clear affinities with Bilgoray and Horodok embroidery. I wonder if this is still practiced or remembered in these villages.
Besides this, Kul'chytska made sketches of the kabat, or jacket, worn in this village, with floral embroidery, or perhaps appliqued ribbon or printed material.
Again, here are a couple of her sketches which have recently been pubished. In this one we can see the skirt and apron as well.
In 1937 in the city of L'viw, there was a 'Folk Costume Fashion Show' [which i would dearly love to go back and take pictures of with a very good digital camera, come to think of it, i would dearly have loved to go around with Kul'chytska and taken lots of photos as well].
In this image, we see a great deal of polychrome embroidery on the ustawka and sleeves.
I would like to find more material if anyone has some.
