After slaving away for hours you're finally ready to reveal your pièce de résistance- a beautiful eldritch scroll covered in arcane images and writing. You've lovingly tea stained the paper, deckled the edges by hand, and used a mixture of wax and powdered chalk to distress the entire piece. It's gorgeous.
And when you finally show it off the first thing you hear is "Hey, I love that font!"
A bit anti-climactic, eh? While the ease of desktop publishing makes creating paper props easier than ever it also means the average person has probably seen a popular font hundreds or thousands of times. That problem gets amplified in niche applications like propmaking. There's a good chance your intended audience is just as familiar as you are with the go-to fonts for fantasy props like Futhark, Quenya, and the ever popular Enochian. When it comes to Lovecraftian props you can add Cthulhu Runes and Lovecraft's Diary to the list of immersion-breakers.
Luckily, Blambot has some interesting free fonts available under a non-commercial license that haven't been overexposed. They're designed to be used as fantasy scripts by indy comic artists, which also just happens to give them the right look for propmaking. Browse around and you'll find some other cool resources as well.
