I did this last year and it turned out great. So, of course, I decided to do it again. All you do is:
1. Clean out pumpkin.
2. Go into a Word Processing Program and find a font that you like.
3. Enlarge font size to the largest size that your paper can hold
4. Print off
5. Tape to pumpkin
6. With a pin poke dots around the edge of your letter
7. Take off paper
8. Carve out letter
