Some of the rugs pictured above are made entirely out of silk. They are about 3 feet by 5 feet and cost around $8,000USD. They were absolutely stunning, albeit a little (A LOT) out of my price range. I also touched a carpet that cost as much as I used to make in an entire year (when I taught public school in the USA). The amount of history and art in that shop was simply incredible.
I, of course, did not go home empty handed. I purchased a beautiful rug, handmade in Turkmenistan around 60 years ago (when the country was known as Turkmen and was part of the USSR). It is lovely, and while it is meant for the floor, I will be hanging it on the wall.
