Thanks , talesof .
There's a small bit of farsi ink handwriting on the back of this one , but no 'tag' .
I've aways bought / checked out oriental rugs via one method , in regards to knotting quantity .
The method is simply KPSI (Knots Per Square Inch) , which are counted at a few (just to make sure) locations on the back of a carpet ; world-wide standard in the rug trade .
I've seen the full range of carpets from very coarse (VC) 30-54 KPSI to super fine (SF) 515-650 KPSI , through the years & it seems like it's all very subjective to every persons' eye .
I've really liked some cheapos & disliked some museum pieces ... sometimes there's no accounting for taste !
There's been lots of deceptive pratices by manufacturers & sales-people , through the years , as to knot-counts per- square-whatever .
Some folks have advertised astounding densities , counting every twist/braid of double,triple,quad or more yarn as a 'knot' , as well as every single knot tied from the back to the surface of a carpet ... this gets into KPCI (Knots Per Cubic Inch) , which is a whole 'nuther critter .
The numbers can make a persons' head spin .
All that hoo-hah being said , I fully agree about the lux feel of a good one underfoot !
