Multi Slit

Rate this posting:
{[['']]}



After Single and double Slit techniques, the obvious extension is to use Multi Slits. The technique is ideal for creating beautiful rhythmic abstract, but much of their success depends on accurate measurements, so take time to draw them up and construct them with care!


1.  Fold a stiff piece of paper in half. Using a pencil, carefully draw, then cut, a series of parallel lines, creating a step effect. Note that the two longest lines are the same length.




2.  Begin the creasing by folding back each step one at a time.





3.  Make sure that all the strips lie neatly side by side.



4.  Fold al the steps backwards in the same way, then open the paper. 
 
5.  Create a series of conventional pop-ups, one below the other, by careffully liftting and creasing the steps one at a time.



6.  Close the pop-up and press it firmly to reinforce all the creases.



The narrower the strips, the better the pop-up looks, through if they are too narrow, they become weak and he pop-up looks deflated instead of pert.



 Tiered  Abstract 
Height 11 cm (4,5 in ) 

The many slits of this remarkable pop-up create the illusion of a number of tiered semicircles. Although the effect is complex, the structure is basedon two simple constraints: the length of each slit and the width of the paper between them.
