It may consist of a length of one or more segments of rope, string, webbing, [[twine]], strap or even chain interwoven so as to create in the line the ability to bind to itself or to some other object - the "load".

While some people possess an innate ability to look at a diagram or photo and tie the illustrated knot, for others the initial stages of learning are best accomplished by being shown knot tying methods by a person who already knows them. Knot tying skills are often transmitted by sailors, [[Scouting|scouts]], [[climbing|climbers]], [[caving|cavers]], arborists, [[Firefighter#Rescue|rescue professionals]], [[fishermen]], and [[surgeons]]. After mastering a few basic knots, the diagrams and photos become easier to interpret and use to continue the learning process. As more knots are learned, patterns begin to become evident in their structure and methods of tying. The learning of knots rewards practice and patience. | ||

Knots are essential in many industrial, occupational, recreational, and domestic settings. Even simple activities such as running a load from the hardware store to home can result in disaster if a clumsy twist in a cord passes for a knot. Truckers needing to tie down a load may use a [[trucker's hitch]], gaining mechanical advantage. Knots can save the [[spelunking|spelunker]] from foolishly becoming buried under millions of tons of rock. Whatever the activity, such as [[sailing]] on the water or [[climbing]] on a cliff-side rock, learning well-tested knots prior to some hazardous activity introduces a critical measure of safety. In addition to safety, appropriate knots can prevent the necessity of cutting lines. | Knots are essential in many industrial, occupational, recreational, and domestic settings.

In [[ropework]], the frayed end of a rope is held together by a type of knot called a [[whipping knot]]. Many types of textiles use knots to repair damage. Macrame, one kind of textile, is generated exclusively through the use of knotting, instead of knits, crochets, weaves or felting. Macrame can produce self-supporting three dimensional textile structures, as well as flat work, and is often used ornamentally or decoratively. | ||
