Jeremy Mickel shares the story of making his first font, which took him about a year and a half.
But then a funny thing happened. I kept correcting and correcting, and all of a sudden I had sanitized the font and there was almost no personality left in it. What I was left with might as well have been VAG Rounded. In a very early draft, I had played with the idea of exaggerating the swellings in the strokes from the original sign. Now I resurrected that, and found the true character of the font.
The result was Router. I also liked this bit:
It's been said that type design is the art of making unequal things appear equal. Noordzij's theory of the Stroke of the Pen is apparent even in monoweight sans-serifs. Flip Helvetica's A, V, or W sideways, and you'll see that the diagonal strokes are slightly unequal. Rotate the O in Futura, which I was always told was a perfect circle, and you'll see why that's not true.
