A friend asked how I do this thing, so I decided to make a tutorial for it! FYI, this is Photoshop CS5. Hope it helps in some way! If there’s anything that completely confuses you, don’t hesitate to ask me. 🙂 

Here is a fullsize version.

(This font’s exclamation point looks too much like an “L,” so I apologize for sounding too excited in my tutorial.)
