Step 1: Materials

pumpkin carving tools - $9 exacto-knife kit (on sale)
- potato peeler
Step 2: Jack-o-lantern
Sorry that when it does not blow vapor it looks a little like a blow up doll for people with a real sick fetish.
I was quite pleased with how it turned out considering I have never sculpted anything in my life before. No comparing to pumpkingutter.com though.
You would be amazed at how much you can cut away without poking through. I think the thinnest spot of my face is still 1/2 an inch thick. One trick I found was to poke a thin exacto blade through the wall until it just sticks through on the inside, then pinch the blade and pull it out to gauge how much wall is left. The blade hole you poked will be invisible.
