Asymetric Mountain

Allmost all the Single and Double Slit techniques so far explained have maintained a central mountain crease in line with the gutter crease behind it. However, this mountain may be moved away from the centre to create an asymmetric effect that is both elegant and surprising. Follow the step-by-step construction with care. The Asymmetric Mountain technique can be used in the same way as conventional symmetrical technique can be used in the same way as conventional symmetrical techniques. The variations show some of these possibilities - remember to draw the complete construction before making any creases or cuts.

Using a pencil, draw a crease down the centre of a stiff piece of paper. Draw two horizontal lines that extend further to the right of the vertical line than to the left. Connect the horizontals with vertical lines, to form a rectangle.

Measure the distance between the centre line and the vertical line to its left. Reproduce that distance, measuring it from the inside of the right-hand vertical. Draw another vertical line at this point.


Erase the central section of the gutter crease. (For clarity, coloured lines have been used here to show which creases are for folding and which are for cutting.)


1.  Having drawn the construction, cut along the brown lines a craft knife.

2. Using an indenting tool and a ruler, indent all the creases, then begin to form the creases individually.

3.  It its often easier to reinforce the from behind. 




4.  Finally, form all the creases simultaneously, flattening the pop-up. Press the pop-up firmly.



In this construction, note how one face of the pop-up step is much longer than the other.
