Maybe the most famous town with it's weaving in Bulgaria is Chiprovtsi. Here is a great collection of pictures and videos of these traditions the way they are practiced today.
for postin this link. The videos were very nice and informative and what a beautiful location.
the location is really nice, although it's in a remote and poor part of the country. I really hope to get the chance to be trained in weaving there...someday maybe
Thanks for the great link!
