A subtle Bnchgra, 1980s-90s, from the Beni Ouarain in the northeastern Middle Atlas displaying a minimalist pattern with a loop pile. This type of pile gives the rug an interesting texture which is achieved by the knots that are left uncut forming loops. Dark horizontal lines run horizontally across the light colored open field; some are continuous while others are revealed as just a fraction of a line, resulting in an elegant, restrained and timeless look. Loop-pile textiles were originally made to use as a cover in cold winters, but can be used as a floor covering. 

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 The knotted rugs from the Beni Ouarain, originally made to use as beds, are known for their exceptional quality of wool, a high pile (up to 4 cm/ 1.57 in) and a classic lozenge pattern in dark brown or black on a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.
