Following the advice of Quentin Crisp and A.F. Stuart, I’m getting bolder; here’s another version of my heading after I’d spent an afternoon hand-lettering the captions for my article.
In Versal Letters, as Stuart & Crisp point out in Lettering for Brush & Pen, the serifs are drawn with a single stroke, which I think works well for a sketchbook heading.
I’ve read that serifs should appear to grow naturally from rest of the letter, rather than looking like something stuck on later but my tendency to draw them with the same care that I’d take in drawing the thorns on a rose or a hawthorn can make them look fussy.
I think the single-stroke serif works just fine.
