Another practical reason for using square paper is the ease of folding. Origami techniques such as valley folds and mountain folds are often more straightforward and precise when the paper is square. The uniformity and regularity of a square shape make the folding process smoother and more controlled. This simplicity is particularly important for beginners and intermediate practitioners who are still mastering the art of origami.

Historical Tradition: A Legacy of Japanese Folk Art

Origami's use of square paper can be traced back to its origins in Japan, where the craft has a long and distinguished history. Traditional Japanese paper, known as washi, is often square, reinforcing the convention that has persisted through the centuries. This historical tradition has further solidified the preference for square paper in origami practice. Even modern practitioners, whether amateur or professional, continue to follow this convention for its aesthetic and cultural resonances.

Versatility: The Multifaceted Nature of Origami

A square piece of paper offers unparalleled versatility in origami. With just a single square shape, practitioners can explore a wide range of designs and techniques. For example, a square can be divided into smaller squares or triangles, enabling complex shapes and intricate patterns to be created. This versatility is a major reason why the square remains the most common choice for traditional origami.

However, it is important to note that origami can be practiced with various shapes, including rectangular, circular, and even non-conventional shapes. Some origami models, particularly those that utilize cutting or multiple sheets of paper, might start with different shapes. Nonetheless, the square remains the most common and practical choice for traditional origami, thanks to its ease of use and the challenge it presents in achieving complex designs from a simple starting point.

Beyond the Square: Exploring Non-Square Origami

While the square is the most common choice for traditional origami, other shapes offer unique challenges and opportunities. For example, a long rectangular piece of paper is often used in money folding, and there are numerous origami figures that start with a rectangular paper. These non-square shapes can be just as rewarding for experimentation and creativity, offering a different set of challenges and opportunities.

A Contemporary Perspective on Square Origami

The popularity of the single-square no-cuts no-glue approach can be attributed to the work of origami master John Montroll. His influence in the early 1980s led to a movement towards simplicity and purity in origami, emphasizing that complex figures could be achieved using just a single square sheet of paper. This approach not only streamlines the traditional process but also adds a new layer of complexity to the art form.

Contemporary origami enthusiasts continue to harness the versatility of the square, combining traditional techniques with modern innovations to create a wide array of shapes and designs. From simple cranes to intricate flower models, the square paper remains a versatile and challenging canvas for origami artists.

Conclusion

While origami can be practiced with various shapes, the square is the most common and practical choice for traditional origami. This preference is rooted in the symmetry, ease of folding, historical tradition, and versatility of the square shape. Whether you are a seasoned origami artist or a beginner, the square offers a perfect starting point for exploring the infinite possibilities of this ancient art form.
