Deletion of Origami techniques

Comment: The techniques of origami are fundamental aspect of the topic, and as such, is a perfectly valid topic for an article.  The article itself is not exclusively a HOW-TO guide.  Listing the various basic folds used is necessary information for a complete treatment of the topic.  At the risk of having an anology go off the rails, and having  thrown at me... We have articles on baseball pitches such as the split-finger fastball complete with photographs showing how to hold the ball, and explaining how the pitch is thrown.  Removing such an article would result in a hole in the coverage of baseball in Wikipedia.  Similarly, for this article.  Some folds form base forms used to construct many other figures. See page 23 from http://books.google.ca/books?id=JbpbyGJdl4YC&pg=PA23 as an example.  Material such as this can be used to expand the article providing more information about origami without it being a how-to manual.  One important point to note is that the article does not explain how to make any origami figures.  If it lurched into that territory, then that material would be fair game for removale from the article, bit still wouldn't be grounds for deletion
