The Antique Square Shape Blue Color Geometric Chinese Baotou Wool Pile Rug is an exceptional piece from the 1920s that showcases the refined aesthetic of early 20th-century Chinese production. Hand-knotted with high-quality wool from Northern China, this square rug features a deep indigo field decorated with a disciplined all-over diaper pattern of stylized quatrefoils. The design is framed by meticulously drawn borders, including a classical Greek key meander and angular cloud-band motifs. Masterful use of oxidized dyes creates a rich variation within the blue palette, giving the wool a lustrous, aged quality. This durable rug offers a sophisticated foundation for contemporary interiors while preserving traditional weaving techniques from the Republican period.
