Hershey's has stencils available on their website for free, to decorate your pumpkins with. They are pretty neat, go check them out! I love Hershey's that is where I got the chocolate cake recipe I have been making for the last 26 years from. :)
Great Halloween site, with lots of printables, and activities for kids, check it out:
They even have Halloween at Hershey Park in the DARK! lol Wish I lived closer, looks like fun!
