A Beni Ouarain rug, 1980s-90s, with a design that has a strong geometric appearance yet still reveals subtlety in the details. It is knotted with the typical wool of the Beni Ouarain sheep and has a dense but slightly shorter pile than usual. The carpet is from the Ait Ighezrane which is one of the subgroups of the Beni Ouarain confederation located in the southwestern part of the territory. These carpets are often recognizable by an open white field, framed by two or three vertically running dark lines. In this example the vertical lines are turned into a zig zag variation on the borders.

The tribal territory of the BENI OUARAIN includes most of the entire high mountain region of the northeastern part in the Middle Atlas. The Beni Ouarain are a confederation of seventeen tribes living in the area. Their territory is bordered by the Jebel Bou Iblane Range in the south and southeast and by the Jebel Tazekka in the north. The knotted rugs from the Beni Ouarain, originally made to use as beds, are known for their exceptional quality of wool, a high pile (up to 4 cm/ 1.57 in) and a classic lozenge pattern in dark brown or black on a white ground. Similar pile rugs with the same color scheme have also been made among other groups in some of the neighboring regions. The rugs of the Beni Alaham, Marmoucha and Ait Seghrouchène are often confused with the ones of the Beni Ouarain even if their patterns are quite particular.
