From Jane Friedman:
The very first thing I’d like to mention is…
S p a c e
Not the book cover cluttered with galaxies of planets, stars and moons, but the one where you can walk into a room and not trip over the dog. A book cover with space allows the imagery and text to breathe. Utilizing space wisely draws attention to the elements that you want potential readers to focus on.
Here is a nonfiction example.
Here is an example of fiction.
And here is an example of poetry in which I’ve taken an extreme perspective. Be sure to take a close look!

PG isn’t totally converted to this cover style.
He wonders how it would look at thumbnail size on a small laptop. Or a tablet?
Or in a thumbnail size along with a lot of other books with colorful covers?
He suggests that anyone designing a book cover needs to understand that good levels of sales on Amazon are almost requirements for success.
