I selected a tutorial on paper airplane folding. I have been interested in this subject since I was a young child and one of my great uncles showed me how to make a paper helicopter. I might decide to do a similar tutorial on my website someday.
I used a search engine to find this tutorial and came up with what is called the Trapezium Paper Airplane.
This tutorial begins by stating what the Trapezium paper airplane model can and can not do. It states that this particular paper airplane is best indoors and glides well if thrown gently. It is not stable enough to do much else.
The tutorial then lists in order the specific folds necessary to make the Trapezium model. Accompanying diagrams help the reader see exactly where the folds should be made.
The steps are:
I found this tutorial useful and entertaining. I learned how to fold paper to make this particular model of airplane. The diagrams were of course the most necessary part of this tutorial since it helps the user visualize and check if the folds are done correctly. I personally would have liked to have seen an animation on the folding process, but that may have been outside the means of the site creator to do so.
The site creator apparently has many more paper airplanes on his site. You can find them all at http://www.geocities.com/bgaschultz/mainplan.html.
Here are my personal favorites:
