Tangled Origami

Tangled Origami

This is one of the flower I took in Royal Melbourne Park using the reverse focus method too. That is the core of a flower, folding itself up like an origami. I have never known that there is such a pattern in flower until that day. Maybe we can call it entanglement or maybe a nicely folded origami.

Although almost any laminar material can be used for folding, the choice of material used greatly affects the folding and final look of the model.

Normal copy paper with weights of 70–90 g/m² can be used for simple folds, such as the crane and waterbomb. Heavier weight papers of 100 g/m² or more can be wet-folded. This technique allows for a more rounded sculpting of the model, which becomes rigid and sturdy when dry.

Special origami paper, often also referred to as "kami", is sold in prepackaged squares of various sizes ranging from 2.5 cm to 25 cm or more. It is commonly coloured on one side and white on the other; however, dual coloured and patterned versions exist and can be used effectively for colour-changed models. Origami paper weighs slightly less than copy paper, making it suitable for a wider range of models.

Foil-backed paper, just as its name implies, is a sheet of thin foil glued to a sheet of thin paper. Related to this is tissue foil, which is made by gluing a thin piece of tissue to kitchen aluminium foil. A second piece of tissue can be glued onto the reverse side to produce a tissue/foil/tissue sandwich. Foil-backed paper is available commercially but not tissue foil. Both types of 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. As these papers are floppy to start with, they are often backcoated or resized with methylcellulose or wheat paste before folding. Also, these papers are extremely thin and compressible, allowing for thin, narrowed limbs as in the case of insect models.

The practice and study of origami encapsulates several subjects of mathematical interest. For instance, the problem of flat-foldability (whether a crease pattern can be folded into a 2-dimensional model) has been a topic of considerable mathematical study.

Technical origami, also known as origami sekkei, is a field of origami that has developed almost hand-in-hand with the field of mathematical origami. In the early days of origami, development of new designs was largely a mix of trial-and-error, luck and serendipity. With advances in origami mathematics however, the basic structure of a new origami model can be theoretically plotted out on paper before any actual folding even occurs. This method of origami design was pioneered by Robert Lang, Meguro Toshiyuki and others, and allows for the creation of extremely complex multi-limbed models such as many-legged centipedes, human figures with full complement of fingers and toes, and the like.
