Stencil

stencil demo

Tired of paying for ammo can cache labels? I've got a stencil design for you -- print it out on a viewgraph sheet, cut out the two stencils (one for a can side, one for the hinge end), cut out the stencil letters (takes about 2 hours with a hobby knife), and you can reuse the critters for years!

On a related note, I've got a writeup on ammo can painting elsewhere.

Another handy stencil design (more detailed than mine, and smaller too). You also can buy these pre-cut (on either card stock or magnetic card) from their store.
