How to Cut a paper woman in half with an envelope trick

This may be a simple paper trick, but on a grand scale, this trick is done on real woman with real saws. This is just the miniaturized (and safer) alternative to the "saw a woman in half" magic trick. Okay, it's not the same exact principle. It's just a sneak paper trick with a little sleight of hand. You'll need a paper drawing of a woman, and envelope and a pair of scissors.
