What is the difference between mason line and mason twine?

Mason line and mason twine are both used in construction and masonry work, but they differ in material and application. Mason line is typically a synthetic, strong, and durable cord used for marking straight lines over long distances, while mason twine is usually made from natural fibers or a combination of materials and is thinner, making it better suited for lighter tasks like tying or bundling. Mason line is often more resistant to weather conditions, whereas mason twine may be more biodegradable.
