Iranian culture and handicraft is known to the world by the name of "persian carpet". This fine artistic handicraft is woven by craftsmen across Iran in various shapes, colors and patterns. Iranian Carpets are woven on a wooden frame called loom. Spinning the vertical threads (wraps) on the loom is the starting point for carpet weaving. Carpet weavers gradually knot the carpet by crossing the colored threads around the Warps according to the pattern to reach the highest wate.
It isn't left unsaid that before the weaving, the fresh wool is trimmed and spun by young girls and ladies in villages to turn into strings. The strings are then taken to dye houses, where which dying is done in a traditional way. The dye workers throw the yarns into a pot of boiling water, turning the yarns into different colors by adding the Natural dyes such as green walnut, pomegranate, rhubarb and ferns.

Among the areas where carpet weaving is still traditionally widespread, Fars province in southern Iran and Kashan city in central Iran have unique motifs and textures. Thus they were registered on UNESCO Intangible Heritage List in 2010. Carpets in Fars province are of interest because they weave carpets without any pattern, and usually embody what they have in mind from their surroundings.
Therefore not any two carpets can be found similar. But the story of carpet is different in Kashan. The pattern of Kashan's carpet is pre-designed with a certain elegance. Patterns such as flowers and plants, animals, foliage, and also historical scenes are drawn and provided to the carpet weavers. The craftsmen also weaves the carpet in a "Persian knot" style. So that on the back of the carpet, there is a set of knots with the exact pattern of the front. But there are short threads on it which have a unique elegance and beauty.
