The use of polychrome squares is an ancient design concept that originates from the Neolithic culture in Africa. This pattern appears in countless forms across Morocco, with each region showcasing its unique style. In this example from the southern Ourika valley, the weaver alternates between wool and industrial fibers to create a distinct sequence of colors. The unexpected shades of blue from synthetic yarns clash beautifully with the dreamy notes of yellow, red, and apricot-colored wool. Irregularly shaped squares are progressively embellished with contrasting motifs. The weaver improvises like a musician, flowing spontaneously with the pattern and expressing its deepest essence.
