I got this idea from the Halloween issue Better Homes and Garden Special Interest Publications 2009. I've been wanting to do this for a couple of years now. They have so many ideas for decorating pumpkins!
I got the stickers at Hobby Lobby. You will need 4 of the big ones. They are in the scrap booking section. You can do what ever colors you want. You will want to use a hot glue gun to help them stay on your pumpkin. I just bought my pumpkin white. It will make a great Halloween centerpiece!!!
