How do I use borders and ornaments on the back cover?
Turn on Show Border or Show Ornament, then select an item from the available library. Borders include a color control; ornaments include color, vertical position, and size controls.
Use these elements to reinforce the front-cover style, not to crowd the text. Keep thin border details away from the cut edge and make sure ornaments do not overlap the blurb, author photo, logo, ISBN, QR code, or barcode space.
