[Untitled]

I began the page. It could use some diagrams or photographs. Maybe it should be broken up into separate pages, and have a tree-like illustration of how the techniques are related. I explained how I make valley folds, mountain folds, and book folds. -- Jasper 20:12 Mar 8, 2003 (UTC)

Added more to the outline, copied (with my permission) from my web site: www.folds.net/tutorial Jasper 02:57 Mar 9, 2003 (UTC)

Valley fold

A separate article was created for "Valley fold," but I merged the content back into here (it was a single line description). Should individual folds get separate articles? I could maybe see grouping them into sub-articles covering basic folds and advanced folds, but giving each fold a separate article seems like a bit much to me. --Alan Au 07:03, 14 November 2005 (UTC)

Yes; I have redone the main article and recreated the valley fold article. the pictures requested should probably be in the smaller articles...Ahudson

[[Origami_techniques]], [[Vally fold]] and [[mountain fold]] are actually the same page which is very confusing. Could someone please correct this? Mahanchian 22:21, 22 February 2006 (UTC)

Comment removed from article

(This page needs LOTS of pictures. I am still in the process of writing it and so many parts will look unfinished for awhile... For those of you that are origami-oriented, could you please work on extending the links for each fold? Thanks, ahudson) [Moved by Heron 21:09, 8 December 2005 (UTC)]

Conjectures

I have removed these conjectures from the article until I find diagrams or folding sequences that confirm them:

• The closed sink creates a hidden rabbit ear, despite minimal unfolding of the paper. It is difficult because it usually involves simultaneously folding over a locking flap that is hidden inside the sink.

• The closed unsink sometimes arises after making a rabbit-ear from paper that is two layers thick, which then must be made symmetrical with one rabbit-ear on each side of a centerline. The result is usually a mirror image of the original closed sink.

Closed sink and unsink can be found in Robert J. Lang's book Origami Insects and their Kin. --Origamikid (talk) 05:20, 23 February 2008 (UTC)

• • The former sounds like a misinterpretation of one fashion of folding a closed sink (or the "rabbit ear" in question forms sideways, in which case it's more of a squash segment than an actual rabbit ear). The 2nd is a relativly common maneuver seen in eg. Butterfly out of that book, but is in no intrinsic relation to a closed unsink. --Trɔpʏliʊm • blah 14:56, 17 March 2010 (UTC)

Other references

I moved these references here, because it was not obvious that they were designed for teaching the techniques, nor was it obvious that they were designed to show how the techniques are related to each other.

• Kunihiko Kasahara. Origami Omnibus: Paper Folding for Everybody. Japan Publications, inc. Tokyo. Copyright 1988 by Kunihiko Kasahara. ISBN 4-8170-9001-4

A good book for a more advanced origamian, this book presents many more complicated ideas and theories, although the author tends to go off on long tangents about random topics. Still lots of good models though...

• Kunihiko Kasahara and Toshie Takahama. Origami for the Connoisseur. Japan Publications, inc. Tokyo. Copyright 1987 by Kunihiko Kasahara and Toshie Takahama. ISBN 0-87040-670-1

Another good book; same comments as the previous author.

Due to significant improvement, do you think we should remove the cleanup tag? --Ahudson

This article seems to have stabilized, and even the comments on the Mountain/Valley fold AfD page seemed satisfied with this article. I therefore removed the cleanup tag. -- Jasper 07:13, 18 February 2006 (UTC)

And one step further, it has nice diagrams. Diagram needed categorization removed. -- ∞Wirelain 05:15, 18 June 2006 (UTC)

Wikibooks?

I don't want to doubt the usefulness of this article (i myself enjoy origami :-) ), but wouldn't this be more relevent as part of a wikibook, rather in an encyclopedia? Let me know what your views are on this. David 23:02, 6 July 2006 (UTC)

You are entirely correct; when this article was created, either there wasn't a wikibook on origami or we just weren't aware of it. There already is a wikibook on origami, I have done a little with it, but any help would be welcome (i've only just started, it was an abandonded skeleton left over by a previous user). I have also had slight misgivings about whther an article like this would be useful even in a wikibook, but that isn't as pressing an issue. Ahudson 16:26, 14 July 2006 (UTC)

Twist fold

I've been folding origami for quite a while, and this is the first time I've ever heard of the twist fold being described as a variant of the stretched bird base, of all things. I can see how the case could conceivably be made, but it's quite a stretch (no pun intended).

OK, I can picture this; it requires a certain subtype of twist fold oft-used by Tomoko Fuse (wherein you twist a conical point, not a flat section of paper) and a certain method for the creation of the base (where something resembling a conical point is produced from two opposite flaps). It's not generalizable for all twist folds, and furthermore the connection to the stretched bp is indeed stretched, so I'll be bold and remoov the note. --Tropylium 16:58, 8 June 2007 (UTC)

Since so many of these folds are so difficult to describe using words, might it perhaps be a good idea if someone were to make some animated GIFs? --WikiMarshall 18:54, 6 June 2007 (UTC)

Pentagon

Under "mid-intermediate skills" of this article, "pentagon" is listed as a "technique". Some models will require the use of nonsquare paper to start with, but the use of a pentoganal sheet of paper to start with isn't classified as a folding technique in origami. Thus I removed it. --Origamikid (talk) 05:20, 23 February 2008 (UTC)

The text about folding pentagons explains that it is usually possible to skip this technique, and start with a pentagonal sheet of paper. But many people (myself included) usually start folding these models from a square. Such people fold the square into a pentagon. In other words, they use a technique to fold the square into a pentagon. I have therefore restored the text about folding pentagons. -- Jasper (talk) 02:10, 23 March 2008 (UTC)
