The granny knot, also known as tate-musubi in Japanese (縦結び, たてむすび), is the conventional knot tied and used in everyday life.
As a binding knot, it is considered inferior to the square knot (ma-musubi), which it superficially resembles. The granny knot consists of two identical half knots tied one on top of the other. It's easier to untie, making it ideal for standard gift wrappings not intended to be transported, as it will be easier to open the gift. If the gift needs to be carried around, use a square knot instead. The tate-musubi can loosen more easily, and items might fall out of the wrapping.
