What is monofilament thread?

Monofilament thread is a single, continuous strand of synthetic material, typically made from nylon or polyester. It is known for its strength, durability, and resistance to abrasion, making it ideal for various applications in sewing, fishing, and crafting. Unlike multi-strand threads, monofilament has a smooth, clear appearance, which can make it less visible in finished projects. It is often used for delicate work, such as quilting or invisible hems, due to its fine profile.
