Macrame (or macramé), is a form of textile-making where fibers or cords are knotted rather than woven or knitted together. Square knots and half hitch knots are traditionally used, and sailors have long used macrame to decorate accessories and parts of ships. Most friendship bracelets are macrame, and this knotting technique can be used to create other styles of jewelry as well. Common materials used in macrame include cords made of cotton or linen , hemp , leather, twisted nylon and yarn.
