Forming strands is a process of creating a rope-like structure from individual fibers. ROPY is a term used to describe the texture of the strands when they are formed, which is usually thick and fibrous. The strands are usually made from natural materials such as hemp, jute, sisal, or cotton. They can also be made from synthetic materials such as nylon or polyester. The strands are usually twisted together to form a strong and durable rope.
