Here are some thoughts from Marla Mallett, correcting some of my statements, which may get your interest :
1/ About the use of metallic wrapped cotton threads in the Malatya storage sack presented in my essay: I said it was a common practice in the Malatya and Sivas area.

Marla adds the following info:
The use of metallic threads is also very common in kilims from the Van/Hakkari area.

2/ About the first Shavak bag showed in my essay, I told: “notice in this close-up the tiny white and blue pick and pick bands edging the bands of overlay underlay brocading. Such extremely decorative pick and pick bands are often seen in Kurdish weavings from Eastern Anatolia and to my knowledge are typically Kurdish. They appear also in Western Anatolian flatweaves and my guess is that such pieces were may be woven by Kurdish weavers who migrated there”.

Marla adds the following info:
"pick and pick" details are very common just about everywhere, and I think it is a mistake to claim that as a sign of Kurdish work. You are right that this detail is common in Western Anatolian weaving, but it appears there on weavings that are Yoruk -- that is, nomadic people with Turkoman backgrounds. There is, in fact, almost no Kurdish weaving in Western Turkey,
and not many Kurds, except in the cities.

3/About the two Iraqi rugs I posted in my topic: “Influence of Yazdanism ……..”

Marla Mallett told:

I think that we need not make a really big issue of what is Anatolian and what is Iraqi, as some of those groups live on both sides of the border.
Tribal divisions may make more sense. Farther from the border more definitive characteristics seem to appear.

The end finishes with wrapped triangular bases appear in work from both countries, for example, but the selvages you showed seem more characteristic of Iraqi pieces.

The only thing in your post that I question is your statement about the row of overlapped knots in the lower part of the one rug. That would not used in an attempt to narrow the rug; in fact such overlapping would tend to have the opposite effect, as more yarn is squeezed into the space. Rugs often tend to be wider at the lower end because there is a natural tendency for a weaving to "draw in" the work proceeds. This happens when the weaver does not allow enough weft ease.

Thanks for your interest,

Marla and Daniel
