This is from the origami mailing list -- July 11, 1994.
From Jeanning Mosely (j9@concentra.com).
I include instructions for the small and great stellated dodecahedron,
made from the same module (30 for each). They are astonishingly easy
-- only seven creases per module. They make wonderful holiday
decorations when made from gold or silver foil. (I usually give one
at Christmas to my son's school teacher.)

I'd just like to mention that Roberto Morassi also discovered
this module independently -- it is published in a book by Fuse on
international modular origami. I'm not sure of the book's exact title.

Great and Small Stellated Dodecahedra
Make thirty of the units described below. Assemble them by sticking
the flaps into the pockets. To make the small stellated dodecahedron,
assemble the units so that 5 isoceles triangles come together at each
point. To make the great stellated dodecahedron, assemble the units
so that 3 isoceles triangles come together at each point. Please note
that ideally, the isoceles triangles should have angles that are 72,
72 and 36 degrees. The construction given produces base angles that
are actually 71.56 degrees. But I don't think many of us can fold that
accurately, anyway. Enjoy!
Fold a square in thirds, making one fold
a valley fold, the other a mountain fold.
