Double Pleat Hexagon Tessellation September 7th, 2006
I just uploaded a new PDF of instructions for folding a Double Pleat Hexagon tessellation; you can 
download it here.
It is released under the CC Non-Commercial Attribution license, which means you can do anything you want with it, other than sell it for $$$, or go around saying it’s your own. (which hopefully you’d be nice enough to not do anyway!)
Let me know what you think. Thanks!
