Although it's been a while since Fallout 4 hit store shelves, it's never to late to revisit the Wasteland and give a big thumbs up to nuclear apocalypse.
The version of Vault Boy pictured above is a bit more complex than the finished version of the linked stencil, mostly because there's a lot of extra shading and pumpkin-shaving involved. But the stencil version of Vault Boy will still have that wonderful, irradiated glow by the time you're done with him.
If you want to rep your favorite Brotherhood, you can do that too. This Brotherhood of Steel stencil will give you the kickass carving pictured below.
