virtual scissors

I made a photoshop document that has three or four vurtual scissors, but I can't post it for you to download. _dont'knwo how or its not possible.

Here is an example. I "cut" one edge off janells pic.
the blue lines above are what the "scissors" document looks like.
It's easy then to select the blue, drag the selection to the paper you want ot cut and delete the selection.
If you want the psd file email me or tell me how to post a file people can download.
