To check a laptop chargers quality it can be difficult but to check a rugs quality, turn it over so
you can see the underside. If the pattern is not as clear on this side as it is
on front, this will at least tell you the rug is not handmade. Machine made
rugs will not have this attribute. Next, if you bend it you should find rows of
knots. This is consistent with a man made rug.You can verify the authenticity of a tabriz rug by knowing what the RAJ
count is. This count is an old method used in Iran to count the knots in a rug.
Sometimes suppliers will quote the count as being higher than it really is.
They do this is because the higher the count the more value the rug has. If
youâ??ve been told that tabris rug you are interested in has a count that is
above 50RAJ, take a look at the foundation. It should be silk and definitely
not cotton. Always check a rugs quality
thoroughly  before buying.
