Hand-lettering has a certain charm computer generated letters just don't have. The letters are never perfectly formed. Spacing is never 100% uniform. And lines are never perfectly straight. All those little imperfections are where that charm comes from.
Take a look at the quote above. This was done rather quickly, with a permanent pen straight from the start. So obviously, things aren't perfectly planned out. Or perfectly drawn in. But it's safe to say, the text is far from boring.
That's partly because pretty much all of the white space is between the letters. To make the words fit the page, I had to get creative with the spacing. It's unpredictable. It breaks the rules a bit. And that's what makes it interesting.
Big blocks of text can be very boring to the eye. So the next time you're faced with a big, boring block of text, let the words fill the space. And forget about making everything perfectly uniform.
