Interestingly, MAHAL (MAHALLAT) rugs and carpets are found with both tribal and curvilinear motifs. This attribute derives from the unique position of the city of MAHALLAT, which is between the cities of ARAK and Delijan, on the path of the tribal people of southern IRAN.
The quality of MAHAL rugs is average. Even though they have loose knots, the structure is strong.
Size & Shapes:
MAHAL (MAHALLAT) rugs and carpets come in different sizes, but the majority of them are mid-size (4 x 6 to 8 x 10 feet). You can also find large rugs up to 10 x 18 feet.
Dark red and khaki are the main colors and the majority of the borders are blue.
Very soft and lustrous wool; thin, tight pile; double weft.
Warp is mostly cotton; weft is either cotton or wool.
Weaver in MAHALLAT use both Turkish and Persian knots. You should check the back of carpet because the quality of the carpet depends upon the number of knots, which varies, but averages around 120 KPSI (30 RAJ).
Many MAHAL carpets have all-over scrolling vine and large palmetto designs-a pattern influenced by Shah Abbas period carpets and often referred to as such. The design has proved to be such an enduring success that it is still copied by many reproduction carpet dealers today. Current trends favoring carpets with all-over designs (particularly among interior designers) have recently boosted the price. Be prepared to pay $4-$10 Per Square Foot (PSF) for a carpet from MAHALLAT. Keep in mind that, as a rule, the higher the KPSI, the greater is the price.
