This Hercule Poirot mask is in .pdf format. It can be printed right from the Web, or you can save it and view it with Adobe Reader--free from Adobe's website. Because of this format, no paint program on your computer is needed. Simply click the mask's image for the mask; a new window will appear, and you'll be able to print it.

As a suggestion, you might want to use "thicker" paper (ie, a paper with a heavier "weight" so it's not too flimsy). A good pair of scissors should be used for cutting out the eye holes. To enjoy or wear mask, you can either use a craft/popsicle stick and glue it on back side near bottom or cut small holes on either side of the eyes and attach string to wear it on your own face!
