Beginners should use natural fiber rope such as jute or hemp in 6mm to 8mm thickness. Natural fibers have good grip and feel, accept knots well, and are comfortable against skin. Synthetic rope (MFP or nylon) is cheaper and machine-washable but slicker and more prone to friction burns.
Beginners entering rope bondage should use natural fiber rope, typically jute or hemp, in 6mm to 8mm thickness and cut into lengths of 25 to 30 feet. Natural fibers have several advantages. They have good grip against themselves, which means knots hold without slipping. They feel pleasant against the skin after conditioning. They are the traditional choice for shibari and most learning materials assume these fibers. Jute is lighter and slightly stiffer than hemp, producing crisp ties. Hemp is heavier and softer, often preferred for longer scenes. Both require conditioning before use, including singeing loose fibers, oiling, and sometimes waxing. Synthetic options include MFP (multifilament polypropylene) and nylon. Synthetics are cheaper, machine washable, and do not require conditioning, but they are slicker, which means knots can slip, and they create more friction heat, which can cause skin burns under tension. Cotton rope is soft and beginner-friendly but stretches and does not hold shape as well as jute or hemp. Whatever rope is chosen, it should be dedicated to bondage and not reused from hardware store applications.
