ManyFolds in Variety

Upper right:

The object has appeared in the preceding article, one of the variations of Ura-Jiro. The structure is composed of alternating iterative folds over pairs of parallel mountain- and valley- creases like knitting ; the method makes its gradually curved spatial shape since the elasticity of paper affects on piled up cells of its folded structure.

Lower left:

This is a symmetric shape with respect to its diagonal (or 'mid-rib') line of the structure ; its iterative folding pattern of creases is almost the same with that of the other. It is also formed into a gradually curved spatial shape because of the elasticity of paper, but this object is not composed of being applied to the 'knitting' method.

Material: a sheet of 15 cm square origami for each, without using adhesives.

Date (the object placed in the lower left): before 2004, certainly; however, its confirmation is still in progress.

[Date (the object placed in the upper right - has appeared in the preceding article -): April 16, 2005 as mentioned before.]

Lower left: folded as "Type #2" in the article 'Ura-Jiro';

Upper right: modified to be larger and gentler in its shape.

Material: a sheet of 15 cm square origami for each, without using adhesives.

Here are eight pairs of images in the front side and the reverse side of samples in his study on the methods/patterns of iterative folding like previous articles those have appeared in this site from the end of last month (March 31) til today (April 16):

% Some images of samples are changed/modified in scale/color from original photos in order to harmonize all the images of eight pairs of objects (as our expectation), while each shape is keeping as it was photographed. %

This has been also affected by the natural variation of the folded paper sheet in its aging over five years by the side of the object in the preceding article:



The upper left: gradually curls into a spiral shape ;

The lower right: looks like a rolled up tongue in the backside.
