Another paragliding website you can try, this one offering oragami paragliders. This site has a secure order page through which you can order their CD. It costs $120, which I thought was a bit steep, but anyway...
The CD features a polite Japanese gentleman with a faint French accent who takes you step by step through the process of folding your paraglider.
The design is AFNOR Standard rated, and requires just a single sheet of glossy paper! A fairly heavy grade mind you.
Why glossy paper, you ask? Turns out it's quite important for reducing the depth of the boundary layer airflow over the upper surface of paper-based paragliders.
Bottom line is you get an extra 2 points of L/D. If you don't know what L/D is, you need to explore my website a bit more. :-)
I must admit I had some trouble locating a stationery outlet that could source sheets of paper the size of my house roof. But really, despite this hassle, what a great idea. A shorter materials list than even the knitted paraglider, beats trying to work with dozens of fiddly bits and pieces that can roll off under the sofa and so on. Viva oragami wings!
A warning. Quite a serious one actually. I was doing some coastal soaring, and didn't take much notice of the rain squall approaching. I should have. The handling became, you know, sort of soggy as the rain drops starting spattering my face. Next thing I knew, I was in the drink, with the sodden remains of my wing plopping down all around me. Splooosh. Plip-plup... Plop, Plip. Pip-pip-pup.
Back to the living-room table, another sheet of paper. Man, folding paper paragliders takes forever. Not to mention the paper cuts. I'd really hate to have to re-do a tandem design, with all that wing area.
