The Fingermen, the secret police in the graphic novel/movie V for Vendetta, headed by the infamous Creedy. Here's how to be one for Halloween!

Step 1: A Bit of Background and Materials List

The Promised Bit of Background:
The Fingermen, being secret police, do not have uniforms. They do however have badges and guns. Leaving the gun part to you, this is how to make the badge.

Materials:
~Cardboard (a flap from a cardboard box is plenty)
~Red, blue, and silver Sharpies
~A glue of some sort (unless you're a Gorilla Glue god, then I would stick to wood or school glue)
~Diagram
~Ruler and pen(cil)
~Scissors and/or X-acto

Step 2: Putting It Together

~cut out three pieces of cardboard using the diagram
~color according to diagram. if you have two-tone cardboard, color on the brown side
~stack and glue in this order from top to bottom: silver - blue - red
~tape into wallet
