I made these posters by using Pumpkin Master’s templates http://www.pumpkinmasters.com/ meant for carving Jack-o-Lanterns. The words are done free hand. You can put the templates on top of carbon paper and trace over them onto the cardstock. I just traced over them with a dull pencil and followed the indentions with a exacto knife.
My daughter Sam made the polymer clay skeleton for her dad and my anniversary last year. It came out so cute!
