We can only speculate on these topics. Indeed there is lots of such speculation in rug literature. We can only know for sure that flatweave structures and techniques have played important roles in shaping designs in tribal textiles. Since we are on such shaky ground when interpreting ideational content in tribal textile art, such matters should play little role in our selections. Anyone who decides to buy a rug because the owner imagines mythical creatures in its spandrels should realize that injecting bits of fantasy into each sales pitch is a time-honored rug merchant's game.
Decorated bags made by Anatolian nomads are personal favorites.
Collectors should keep in mind that the textiles currently in vogue are rarely the best bargains. Prices inevitably rise after any group of rugs or weavings has been researched and published widely. Then fashions change as the next group is promoted. Incidentally, fine ethnographic rugs and other textiles are never priced by the square foot. Small pieces can be more expensive than large rugs.
