If you can make a book jacket, you're basically a professional designer! Book jackets include not just the cover but a spine and a back cover, meaning you have to have the blurb and some select quotes as well. Who knows, you might just find one of your designs in a certain bookshop near you sometime soon!

Book jackets of any genre are more than welcome here! We're fully supportive of your aspirations to become a graphic designer, and we wish you luck on your journey.

Dimensions aren't set for this, and the spine can be as small or as big as you want it to be! In these examples the designers have included extra bits of information on the sides of the jackets; that's assuming that the book is hardcover, and for this, you don't have to do it. You can if you want, though!
