![]() The paper is then collapsed to form a square shape with four isosceles-right triangular flaps. The preliminary fold or square base consists of a diagonal mountain fold that bisects two corners of the square and two perpendicular valley folds that bisect the edges of the square.Because of these restrictions, proponents of the theory have devised alternate methods of folding more complicated steps that have very similar results. Origamis that are done by creating only one fold at a time are called pureland origami. This can be achieved with higher accuracy by folding and unfolding two reference creases through the center. The blintz fold is made by folding the corners of a square into the center.The helmet base consists of a diagonal valley fold that bisects two corners of the square and two perpendicular valley folds that push two corners of the triangle to the third one.The kite base is merely two valley folds that bring two adjacent edges of the square together to lie on the square's diagonal.The radial pleat fold is an angled pleat fold, usually with a focus point on an edge or corner.The pleat fold is several evenly-spaced parallel mountain and valley folds.The cupboard fold is two valley folds that push the edges of the paper to the middle.The book fold is a valley fold that folds the paper by the middle and entirely covers the side up.The more the number of folds is high, the more the techniques involved in the construction is complex. Models are typically classified by the number of simultaneous folds to realize. The windmill base, helmet base, umbrella base and pig base are found in traditional models, but not used or accepted as widely. This technique allowed folders to multiply the number of points on the base, and is referred to as "blintzing" the base. ![]() One of the new techniques they developed was to fold the corners into the center (a blintz base), fold the base, and then unwrap the extra layers of paper. In the 1960s, paperfolders started trying to find new bases to create more complex models. ![]() They all share the same symmetry, and certain structural properties. These bases are referred to as the classic bases, and were used as the primary design technique until the 1960s. Most recently published books only assume the knowledge of these bases however, some authors still use unconventional bases. While some of them are rarely used, there are six that are used quite frequently: the waterbomb base, preliminary fold, kite base, fish base, bird base and frog base. Traditional origami models were often developed from similar patterns. However, the use of a base does, to a certain extent, limit what can be done with the model. The usage of a base has many benefits the folding sequence will be easier to remember and create diagrams for, and further models can be developed from the same base, or from slight modifications thereof. In origami, a model base is the structural skeleton of an origami model in its simplest form.
