The Origami Forum

Hi

I'm looking for some hedgehog diagrams of an intermediate to complex level. Any pointers to books or web sites would be much appriciated.

The usual answer - Check the origami database:

If you're looking for the spiny ones, John Richardson has one in Kenneway's Origami: Paperfolding for Fun, and there's another one by Kouji Nakagawa in the 8th Tanteidan Convention book.
