Macrame is a type of textile made by knotting processes rather than weaving or knitting. The square (or reef knot) and various combinations of half hitches are the fundamental macrame knots. Sailors have historically used it to cover anything from knife handles to bottles to ship pieces, especially in intricate or ornate knotting styles. Cavandoli macrame is one type that is used to create geometric and free-form designs similar to weaving. The Cavandoli style is primarily performed with a single knot, the double half-hitch knot. When working the left and right portions of a balanced piece, reverse half hitches are occasionally employed to preserve balance.
