Origami/Bases

From Wikibooks, the open-content textbooks collection

A base is the structural skeleton of an origami model in its simplest form. 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. However, the use of a base does, to a certain extent, limit what can be done with the model.

[edit] Common Bases

Traditional origami models were often developed from similar patterns. While some of them are rarely used, there are six that are used quite frequently. Most recently published books only assume the knowledge of these bases; however, some authors still use unconventional bases.

• Waterbomb Base

• Preliminary Fold

• Blintz Base

These four are referred to as the classic bases, and were used as the primary design technique until the 1960s. They all share the same symmetry, and certain structural properties:

• Kite Base -- one point

• Fish Base -- two points

• Bird Base -- four points

• Frog Base -- five points

In the 1960s, paperfolders started trying to find new bases to create more complex models. 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. This technique allowed folders to multiply the number of points on the base, and is referred to as "blintzing" the base.

[edit] Other Traditional Bases

These bases are found in traditional models, but not used or accepted as widely.

• Windmill Base

• Helmet Base

• Umbrella Base

• Pig Base
