Designing a book cover with BookBildr is very easy:
The first page of your book project is the front cover
The last page of your book project is the back cover
BookBildr will automatically generate a cover file when you place your printing order but you can preview the cover by using the Spread Layout mode:
You can customize the book spine by clicking on the Spine menu entry. From there, you’ll be able to add a background color to the spine and add some text.
Please note that saddle-stitch and coil-bound books do not have a spine.
