Start with a skinny triangle, and fold a line perpendicular to one of the long sides. Where that line hits the side across from it, again fold a line perpendicular to that side as well. Repeat until it gets too small to continue. If you're looking for something a little more involved, I have an old model from 2007 which is similar in concept to the models you mentioned, but still relatively simple: https://www.youtube.com/watch?v=Vox2bKkrEyo --Andrew ______________________________ http://www.flickr.com/photos/ahudson http://ahudsonorigami.wordpress.com/
