Hello Rich and Chuck,

Thanks for your insights about bleeding vs fading of synthetic dyes, both of which afflict the red seen in the two chuvals. Here again are images of the Yomud chuval on top of the Yomud main carpet (chuval above, main carpet below, in each image). Bleeding of the red can be seen in the main border of the chuval, and is even more evident when viewed from the back. In contrast, there is no bleeding (or fading as shown previously) of the red in the main carpet. Again, although the absence of fading and bleeding isn't by itself diagnostic, the weight of evidence thus far seems consistent with natural dyes in the main carpet.

Happy holidays,

David
