If you don't have access to a printer, then you can draw your template onto a piece of card. An easy one to start with might be the Halloween mask. (Hint: the easiest way to make sure that your mask is the same on the left side and the right side is to fold a piece of paper in half and then draw your template. When you cut it out, the two sides will be identical!)

Once you have printed out (or drawn) your template, cut it out. You will also need to measure and cut out the eye-holes.
