Origami Preliminary Base
- Start with a square sheet of paper with the colored side facing up.
Fold the paper along the diagonal in both directions to form an X shaped crease. Unfold.
- Flip the paper over so the white side is facing up.
Fold the paper in half left to right. Unfold.
- Fold the paper in half top to bottom.
- Push the right and left edges inwards towards one another. A flap of paper will come towards you (red dot) and another flap will be created behind the model (blue dot).
- Swivel the front flap to one side. Swivel the back flap the other direction. Use the location of the dots to help visualize the process.
- Done! The origami preliminary base looks like a square that is ¼ the size of the original paper. It has a total of 4 flaps. The typical orientation is to have the flaps arranged two on the left and two on the right.
|The preliminary and waterbomb bases are the bread-and-butter of the origami world. There are many origami models which start with these two bases. In fact, the two bases are inter-convertible: if you invert the preliminary, it will become a waterbomb base. The opposite is also true, a waterbomb base can be inverted to form the preliminary. The only issue being that the colors (color or white) would be inverted too.|
The instructions shown here is just one of the many ways to make the base. You can see this base being used in this Fluted Diamond ornament.
