I'm using Affinity Publisher to print a Blurb tradebook (6x9), and I'm having issues creating a cover for the book.
When I put in the cover specifications (See attached image) when creating a new document, I don't have a place to input the Gutter/Spine measurements. This means when I hit "OK", the document looks like a wide rectangle with no spine in the middle, making it difficult to see if the title will be off-center.
There don't seem to be any good tutorials for creating a Blurb book (or any book from start to finish) with Affinity, but if there is one, I'd love a link.
Thank you!
