Take a picture of yourself, blow it up big enough to cover the block. If you cut it out, you will each have your own "outline/siloutte." You can print these out on copy paper, it is just for a template :D
If you want a generic one, choose a picture from somewhere, and print it out to the correct size.
You can copy and paste these to a word document, and adjust the height and width too :D:D:D
