We're traditionalists in the pumpkin milieu, as you can see by my creations this year. Actually, #1 son designed them, I merely executed his "vision".
But for a whole 'nother world of Pumpkin Art, check out the Mount Rushmore of jack-o-lanterns (here's an example of our scariest world leader). Also have a look at Extreme Pumpkins -- and here's a site with some cool stencil patterns (I love the hangman). Stock up on toothpicks before you try these, Rudy.
