How do I create a full print-ready (paperback) cover?

Creating a full paperback cover (with front, spine, and back) is a two-step process:

1. Customize the Front: First, go to the front cover editor. Select a print trim size (e.g., "6.00x9.00 inch") from the "Change Trim" menu. Make your text and design customizations, and click the "Remake Cover" button.
2. Design the Back & Spine: Once the front cover is rendered in a print size, the "Print-Ready Spine and Back" button will become active. Clicking this will take you to our back cover editor, where you can design the rest of your paperback.
