The discovery of all possible ways to tie a tie depends on a mathematical formulation of the act of tying a tie. In their papers (which are technical) and book (which is for a lay audience, apart from an appendix), the authors show that necktie knots are equivalent to persistent random walks on a triangular lattice, with some constraints on how the walks begin and end.
A 3-dimensional rendering of the ribbon knot , showing the ribbon property. In the mathematical area of knot theory, a ribbon knot is a knot that bounds a self-intersecting disk with only ribbon singularities. Intuitively, this kind of singularity can be formed by cutting a slit in the disk and passing another part of the disk through the slit.
Rhythmic gymnastics routines require the ribbon to constantly be in motion and create defined shapes. [3] The ribbon is generally held by the handle with the thumb and pointer finger extended. [5] Because of the ribbon's length, the gymnast can easily become tangled in it or cause knots to form; juniors and beginner gymnasts may use shorter ...

The second method involves introducing a short piece of rope of the same type as the main rope, and cutting that instead. This can be accomplished by many sleight of hand tricks but attaching it to the main rope disguised as the loop of a knot is the most common method. When the performer removes the knot, the original rope is completely uncut. [1]
To make, cut a quilt into a trapezoid shape, finish the edges and sew ribbon to create a tie. Use a scrap piece of the quilt to cut out an oversize letter "Q" and stitch it to the front of a T-shirt.
Hitching tie – simple knot used to tie off drawstring bags that allows quick access; Honda knot a.k.a. lariat loop – loop knot commonly used in a lasso; Hoxton knot – a method of arranging a scarf about the neck; Hunter's bend a.k.a. rigger's bend – joins two lines
Mizuhiki on an envelope — this photo shows gold and silver kekkon mizuhiki adorning a shūgi-bukuro, commonly given as a gift at weddings.. Mizuhiki (水引, lit. ' water-pull ') is an ancient Japanese artform of knot-tying, most commonly used to decorate envelopes, called kinpū, which are given as gifts during holidays like Japanese New Year (and are then called otoshidama) or for special ...
