Been there, done that. I don't remember off the top of my head which stellation it was and I'm not sure where I got the pattern for it... this was probably five years ago. It actually was a truncated version, because it was a star to go atop the tree so I lopped off the bottom spike.

As I recall it involved only twelve pieces. Looked pretty good, though I did it fairly hurriedly and it wasn't as neatly done as it could have been. And I used ordinary bond paper (pieces printed in gold on my computer's printer), so it wasn't particularly durable.

Another year I did a unit origami piece for the treetop, which actually survived a few Christmases.
