Stencil Help

Hey, i'm reposting this here. Maybe it will work this time.

Alright guys, i'm just gonna cut to the chase because i've been looking for an answer to this question for the entire day. The problem is this question might not make sense at first.

"How do you make a stencil bigger on Adobe Elements or GIMP?"
What i mean is i've seen Tut's on how to create big stencils by printing different sections of the picture on to different pieces of paper. Here is an example of what i'm talking about: http://video.google.com/videoplay?do...arch&plindex=0The thing is i have a Mac so...I want to know how this can be done on those programs.

So PLEASE HELP ME!!! PLEASE!!!!

Do you have your image ready? let me know what stage you are at.

Photoshop:
Image -> Image Size

If the dpi stays the same and you blow it way up then it will print on multiple pages.

You can also scale it up in the Page Setup like they showed in the movie.
