Perfect — a family heirloom cookbook at 80 pages is the Etsy/KDP sweet spot, and it works in both formats. Here is the full build. (1) Concept and target buyer. (2) Theme & mood: Sunday roast at Grandma's, tea-stained cards, handwritten marginalia. (3) Visual style guide: soft cream paper, handwritten-feel display font, warm tungsten food photography. (4) Complete chapter + page map: front matter (cover, title, dedication, how-to-use, pantry & basics, dietary legend), 6 body chapters in eating order, then alphabetical index, ingredient index, conversion charts, contributor credits, and lined 'your notes' pages. (5) The locked 9-zone recipe-page anatomy with one fully written sample page. (6) Cover + back-cover blurb + KDP spine spec. (7) A 130-char SEO title, marketplace description, 13 tags, paste-ready Midjourney prompts, and a print/export checklist (8.5x11 printable + 6x9 KDP, bleed, 300 DPI, embedded open-source fonts).
