Sunny has a sheet of stamps that he wants to separate into individual stamps. How can he do it with the fewest possible tears? Assume the stamps are all rectangular, all the same size, arranged in a uniform rectangular grid, each stamp is perforated along all 4 edges, and the sheet is very thin.

Gotta ask: does the size of the grid matter?
Or should we assume m by n?

Even a thin piece of paper has a finite number of possible folds...

edit - nevermind, you could do a fan fold.
