', p.12-3. Penguin. . Designs and motifs are also affected by and affect pile depth: "A carpet design with a high knot density is better adapted to intricate and curvilinear designs, which of necessity must have a shorter pile length to avoid looking blurry. A carpet with a lesser knot density is better adapted to bold, geometric designs and can utilize a long pile for softer, more reflective surface that appeals to the sense of touch."Denny, Walter B. (2014). ''How to Read Islamic Carpets'', p.43 & 61. Metropolitan Museum of Art. .
