You may not be a collector, but like anything, with carpets you want to get the best bang for the buck. And you want to buy a carpet that "lives". Many of these mass produced carpets have no "life".
Here's a nice Tabriz I bought when I was young and foolish.
The color and design are truly alive in different light situations.
And the knots and knot count is important. I didn't count here, but I think this is about 600 per inch. And note how pretty and even the knots are.
Lots of Tabriz carpets today are even machine made. Stay away from those. And IMO if the carpet is completely "dead" you might as well buy wall-to- wall.
