High in Morocco's Middle Atlas Mountains, the Beni Ourain tribal confederation has for generations hand-knotted thick, undyed sheep's-wool rugs to survive cold mountain winters. Woven by Amazigh women on simple looms, each piece uses only the natural fleece itself — warm off-white wool set against the same sheep's darker charcoal-brown hair, with no dyes at all.

Across the deep, tousled shag runs a spare lattice of diamonds and lozenges, drawn in irregular hand-woven lines rather than ruled geometry. These abstract marks function as protection symbols, passed down through oral tradition. The result is a textile language built entirely from restraint: two undyed wool tones, one grid, and generous open field.
