Gilim is one of the traditional and enchantingly beautiful handicrafts of Iran whose oldest sample dates back to the Parthian era. Although more than thirty different types of Gīlīm have been discovered, it is possible to classify Iranian carpets into three categories:
2-The group of one-sided or ‘Sūmak’ Gīlīms that are woven by means of ‘Pūdpīcheshī’ (weft-twisting) method. These Gīlīms are thicker than the ordinary ones and have weft, twisted wharf and thin warp. Since the surplus of twisted wharf is hidden at the back of this type of Gīlīm, it consequently becomes one-sided and thicker than Gīlīm, and the colored threads spread miscellaneously on the back side.
3-And finally the third group of Iranian Gīlīms is ‘Golbarjasteh’ (flower-embossed) Gīlīms that are one of the fascinating and most significant handicrafts of Iran, due to its considerable beauty and delicate simplicity. The weaving equipment ink ‘Golbarjasteh’ is the same as ordinary, two-sided Gīlīms, but it’s discrepancy lies in its weaving method. In this method the foundation (background) of the Gīlīm is woven using the standard Gīlīm-weaving method, but in flower-embossed areas the carpet-weaving procedure is employed (knotted and fuzzy). The materials used in ‘Golbarjasteh’ Gīlīms are cotton, wool, and silk yarn that can be utilized by the artists according to their tastes or the customer’s orders. The finest samples of Golbarjasteh Gīlīms are found in Īlām, Kohgīlūyeh, Markazi and Fars provinces.
