From Monday through Thursday of this week, Sight Unseen is featuring a documentary project by British sculptor Carly Mayer, who indulged her personal curiosity about the factories surrounding her home in Brighton, England, by inviting herself over to photograph their inner workings. Today she explores the making of the humble ratchet strap, overlooked by many but essential to some. "Personally, I had never given the humble ratchet strap much thought," Mayer writes. "It serves a purpose not universal or common, but practical and specialist. Most of us would never have any need for one. As I ventured into the factory, I was greeted by several heavy-duty sewing machines, and unlike the typical assembly line, a more fractured setup, with pods of people working on specific tasks. The stacks of brightly colored, coiled strapping looked like massive sweets in an out-of-scale candy shop."
