Origami (Japanese: 折り紙 ori, to fold, and kami, paper lit. "folding folding paper origami paper") is the art of paper folding. The goal of this art is to create a given result cheap origami paper using geometric folds and crease origami paper folding with dollar bills patterns. Origami refers to all types of paper folding, even those origami paper wholesale of non-Japanese origin.
Origami only uses a small number of different folds, but they can be combined origami paper folding instructions in a variety of ways to make intricate designs. In general, these designs begin with a square paper origami sheet of paper, whose sides origami paper to purchase may be different colors, and usually proceed without cutting the paper. Contrary to most popular belief, traditional Japanese origami, which has been practiced since blank origami paper the Edo origami paper 5-7/8' square era (1603-1867), has often been less strict about these conventions, sometimes cutting the paper during the creation of the origami paper maker design (Kirigami 切り紙) or starting with a how to make origami paper rectangular, circular, triangular or other non-square sheets of paper.

The origins of origami are disputed, but origami was certainly paper boat origami developed more in Japan than anywhere paper dragon origami how to fold else. Origami was mostly a traditional art for the amusement of children until Akira Yoshizawa spurred a renaissance of the printable origami paper artform with his new advancements, including wet-folding and the Yoshizawa-Randlett system of how to make paper origami diagramming. make paper crane origami In the 1960s the art of origami began to spread out, first with modular origami and then with paper popper origami various movements developing, including the kirikomi, purist and pureland schools of thought.

Although almost any laminar material can be used for folding, the choice of material used greatly manufactures origami paper affects the folding and final look of the model.
Normal copy paper with origami + how to make a 8 point star + 12 pieces of paper weights of 70–90 g/m² can be used for simple folds, such as the crane and waterbomb. Heavier origami paper boats weight papers of origami paper boxes 100 g/m² or more can be wet-folded. This technique allows for a more rounded sculpting of origami paper squares the model, which becomes rigid and sturdy when dry.

Special origami paper, often also referred to as "kami", is sold writing stationary kit origami paper in prepackaged squares of various sizes ranging from directions for tubular origami paper hearts 2.5 cm to 25 cm or more. It is commonly coloured on one side and white on the other; however, dual coloured easy paper crane origami and patterned versions exist and how do i make an origami paper boat can be used effectively for colour-changed models. Origami paper weighs slightly less than copy how to fold an origami paper heart paper, making it suitable for a wider range of models.
Foil-backed paper, just as its name implies, is a sheet of how to make a paper origami dragon thin foil glued to a sheet of thin how to make origami paper kunai paper. Related to this is tissue foil, which is made by gluing a thin piece of tissue to kitchen aluminium origami paper box foil. A second piece of tissue can be glued onto the reverse side to origami paper drinking glass produce a tissue/foil/tissue sandwich. Foil-backed paper origami paper roses is available commercially but not tissue foil. Both types of origami paper sheets foil materials are suitable for complex models.
Artisan papers such as unryu, lokta, hanji, gampi, kozo, saa have long fibres and are often extremely strong. paper folding mini 3d origami hearts As these paper heart origami papers are floppy to start with, they are often backcoated or resized with methylcellulose or wheat paste before folding. Also, these papers 'make origami paper boxes' are extremely thin and compressible, allowing for thin, narrowed limbs as in the case of 1000 paper origami cranes insect models.
Mathematics of origami
The practice and study of origami encapsulates several subjects of mathematical interest. For directions for tubular paper origami hearts instance, the problem of flat-foldability (whether a crease pattern can be folded into free paper origami guides a 2-dimensional model) has been a topic of considerable mathematical study.
Significantly, paper how to fold an origami paper crane exhibits zero Gaussian curvature at how to make origami paper lanterns all points on its surface, and only folds naturally along lines of zero curvature. But the curvature how to make paper origami boxes along the surface of a non-folded crease in the paper, as is easily done with origami animal skins paper wet paper or a fingernail, no longer exhibits this constraint.
Folding a origami lady bug paper flat model from a crease pattern has origami ladybug paper been proven by Marshall Bern and Barry Hayes to be NP complete. 
The problem of origami paper cranes meaning rigid origami ("if we replaced the paper with sheet metal and had hinges in place origami paper cup of the crease lines, could we still fold the model?") has origami paper hat great practical importance. For example, the Miura map fold is a rigid fold that has been used origami paper heart to deploy large solar panel arrays for space satellites.
Technical origami, also known as origami sekkei, is a field of origami that origami paper wallet has developed almost hand-in-hand with the field of mathematical origami. origami paper western kentucky In the early days of origami, development of new designs was origami quilling paper folding largely a mix of trial-and-error, luck and serendipity. With advances in origami mathematics however, the basic structure of origami star paper a new origami model can be paper folding tiny 3d origami hearts theoretically plotted out on paper before any actual folding even occurs. This method of origami design was paper origami dogs pioneered by Robert Lang, Meguro paper origami rose Toshiyuki and others, and allows for the creation of extremely complex multi-limbed models paper origami wolves such as many-legged centipedes, human figures with full complement of fingers and paper rolls origami toes, and the like.
The main starting point for such technical designs is the crease pattern (often abbreviated as 'CP'), which is essentially the layout of printable asian origami paper rectangle paper origami the creases required to form the final model. Although not intended as a substitute for diagrams, folding from crease tacky origami paper patterns is starting to gain in popularity, partly because what origami paper cranes mean of the challenge of being able to 'crack' the pattern, and also partly because the crease pattern is often the only resource available to fold a given model, should the designer choose not to produce diagrams.
Paradoxically enough, when origami designers come up with a crease pattern for a new design, the majority of the smaller creases are relatively unimportant and added only towards the completion of the crease pattern. What is more important is the allocation of regions of the paper and how these are mapped to the structure of the object being designed. For a specific class of origami bases known as 'uniaxial bases', the pattern of allocations is referred to as the 'circle-packing'. Using optimization algorithms, a circle-packing figure can be computed for any uniaxial base of arbitrary complexity. Once this figure is computed, the creases which are then used to obtain the base structure can be added. This is not a unique mathematical process, hence it is possible for two designs to have the same circle-packing, and yet different crease pattern structures
