This is the stencil I made for that funkin I just did. I'll upload his bride soon I have to re-do her stencil.

Anyway all you need to do for this is:
1. Decide how big you want it (I think I made him about 7-8 inches)
2. Print it out
3. Lay it on some black duct tape and cut out all the white. It helps if you use a small piece of tape on the top and bottom of the stencil to hold it in place while you cut it out.
4. Carefully cut the finished product into smaller more manageable pieces and stick them to your pumpkin.

It should look something like this when you're done...
