Here are two new book covers in very different styles. The first title for Jackie Collins is done with a bold brush for a casual contemporary look. The second is a children’s book title done in a style of formal calligraphy designed to have many of the qualities of a font.
I start these formal styles with a calligraphic pen, and then modify using a combination of hand techniques and computer. See more examples of lettering for book covers in the titling section of my website here.
