Dan Mall, per il blog di Typekit, dà alcuni consigli di tipografia concentrandosi sulle lettere:
When modifying letterforms, it’s safer to modify the bottom than the top in order to preserve legibility. The shape of a word—which we’ll get into in just a minute—is generally more unique at the top because there’s more variation in ascenders and majuscules; keeping the top intact preserves that uniqueness. Notice that all of these great pieces of lettering have most of the ornamentation and variation at the bottom rather than the top.
