A little while back I needed a stencil font for the exterior of USAAF aircraft. The insignia pattern is one thing, but finding a stencil pattern that matches USAAF aircraft is nearly impossible, at least I never found one that was right for each character. So, I broke out a few utilities and made up some new ones.
If anyone wants to know how, just check out the "Font Creator Program," by High-Logic. I guess I *could* post my stencil font, if anyone needs it. You can make just about anything into a font. I have even gone so far as to put brush strokes into fonts. That kind of detail helps to accent scale.

I love this stuff.
