As the judge for the yearly pumpkin contest I reject a ton of pumpkin photos. Many of the rejected ones rely too heavily on the use of props and silly stuff. Putting a Yankee's cap on your pumpkin is kind of stupid and not scary. I am tired of it.
One type of props that I do approve of is scary looking vegetable props. I don't want to see you using potatoes for a nose or anything but a big red pepper as t tongue is cool enough to use in my book.
When I am not carving pumpkins, I run a bulletproof vest company. BulletSafe Bulletproof Vests are the value leader in body armor. We are very popular with people like armored car operators and ATM repairmen.
