Posición del papel: Color arriba.

Papel de un solo color.
Pliegues y líneas básicas: Todos los pliegues tienen una representación gráfica que esta compuesta por un tipo de línea y una flecha asociada a ella, así que simpleme nte viendo el tipo de flecha o de líne a sabremos como debemos doblar. Esto puede ser muy útil en aquellas zonas del libro donde por su pequeño tamaño no se sepa con seguridad si la línea que aparece es valle o montaña.
Tipo de lín ea.
Proceso de plegado.
E x plicación .
Pliegue valle.
Consiste en doblar hacia delante, llevando un lado del papel sobre el otro.
Pliegue Monte.
Consiste en doblar hacia atrás, llevando un lado del papel sobre el otro.
Plegar y desplegar. ó
Marca.
Esto en realidad no es un pliegue, son dos que se hacen uno tras otro. Consiste en doblar, bien sea en monte o en valle y acontinuación desdoblar. El resultado que queda es una marca.
Las marcas son siempre el resultado de plegar y desplegar algo.
Pliegues compuestos: Consiste en un pliegue valle inmediatamente seguido por otro en monte. Su flecha asociada es quebrada y apunta en la dirección del valle.
Pliegue escalonado. y
Es una forma de invertir una punta, de forma que al terminar el hundido el modelo quede totalmente plano.
Pliegue hundido.
Es un pliegue muy similar al hundido, que generalmente se hace en las puntas para cambiarles la dirección.
Pliegue hendido.
Pliegue Vuelto.
Como en el caso anterior este proceso permite cambiear la dirección a una punta, pero en vez de doblar hacia el interior, se hace al exterior.
Pliegue en oreja de conejo.
Es un sistema sencillo para "adelgazar" una punta y al mismo tiempo cambiarla de dirección.
Doble oreja de conejo.
Consiste en dos orejas de conejo que se hacen al mismmo tiempo por cada lado de la punta.
Estirar.
Se coge el modelo por donde indican las manos y se estira hasta obtener el resultado mostrado en el siguiente paso.
Otros Símbolos importantes: Repetir tantas veces como rayas tenga la flecha.
Partes iguales.

The completed chess set. From left to right, the pieces are the pawn, the bishop, the knight, the rook, the queen, and the king. Actually, the pawn shown in the photo is an older version that did not have the long flaps tucked inside the model. The premise behind this series of chess pieces was to design a chess set that (a) could be folded from the same sized squares, (b) were 3D, and (c) were easily distinguishable. The first piece to be designed was the knight, followed by the pawn, the bishop, and the queen. The king caused me all sorts of problems, and I’m actually still not happy with its look. The rook came almost as an afterthought.
