A knot, or tie, is a method of fastening or securing two or more objects together, often using a length of rope, string, or fabric. Knots are commonly used in various activities, such as sailing, climbing, and crafting, to ensure safety and stability. Different types of knots serve specific purposes, such as the bowline for creating a fixed loop or the square knot for joining two ends of rope. In addition to practical uses, knots can also be decorative. For example, neckties and bow ties are worn as fashion accessories, often associated with formal attire. Learning to tie different knots can be a useful skill in everyday life, enhancing both functionality and style.
