I do like the idea of painting faces on the pumpkin rather than cutting them. The pumpkins above from bhg.com might be less messy -- I guess. Paint is messy, too but it does look good. The only negative is that you can't light your pumpkin if you don't carve it.
These pumpkins with false teeth are still my favorite. The people at marthastewart.com came up with this great idea.
Todaysfabulousfinds.blogspot.com found these pumpkins simply made from blocks of wood and decorated with ribbon. It looks like they glued a stick to the top.
