folded book



Lilias:

Well, think of an accordion with each "page" a perfect square. Then think of
every vertical fold as a "mountain" with the valleys a diagonal 45 degree
(lower left to upper right) fold.

If you'll just do this and then fold it up, one fold at a time (don't get
confused and try to collapse the whole thing at once as you might do for a
regular accordion) - it spirals.

Try it.

Pat
