Modern Hermès scarves measure 90 cm × 90 cm, weigh 65 grams and are woven from the silk of 250 mulberry moth cocoons. All Hermès scarves are hand printed using multiplesilk screens and the hems are all hand-stitched. Forty-three is the highest number of screens used for one scarf to date (the charity scarf released in 2006) one screen for each color on the scarf. Since 1937, Hermès has produced over 2,500 designs, with the horse motifs being particularly famous and popular. Production of scarves has ranged from 250,000 in 1978 to 500,000 in 1986 to 1.2 million in 1989. During the holiday season in its Paris boutiques, on average, one scarf is sold every 20 seconds. Besides being known for its texture and design, Hermès's scarves have another unique trait that is unprecedented; that is its scarves made with a scent.
