How to Create a Children's Book with AI Images in One Weekend

My niece's fifth birthday was three weeks away when I had the idea: make her a personalized children's book featuring a character that looked like her, going on an adventure based on her specific interests.

Custom illustrated children's books from professional illustrators cost $800–$2,000 and take months. I had three weeks and approximately zero illustration skills.

I made the book in one weekend. It took two days of focused work, cost $10 in Midjourney credits, and produced something my niece has read approximately forty times since her birthday.

This is the complete guide to how I did it, and how you can too.

Weekend Overview: The Plan

Friday evening: Story outline and character design Saturday: Generate all illustrations Sunday: Layout, formatting, and print preparation

Total active work time: approximately 10–12 hours.

Step 1: Write the Story First (Friday Evening)

The most important step happens before you open any AI image tool: write the complete story.

This sounds obvious, but many people start generating images and then try to write story pages around them. This creates two problems: inconsistent image style and a story structure that serves the images rather than the other way around.

Write the story completely first. For a standard 32-page picture book:

• 14–16 spreads (double-page layouts)
• 1–2 sentences of text per spread
• Clear story arc: introduction → challenge → adventure → resolution
• One main character, 1–2 supporting characters

My story: A girl named Maya who can talk to plants. She discovers that the old oak tree in her garden is sad and goes on a journey to find what the tree misses. Total: 14 spreads, around 300 words of text.

Character Design Notes

Write detailed character descriptions before generating anything:

• Age, approximate appearance
• Key visual signature elements (what makes them recognizable — a distinctive hat, a specific color scheme, an unusual hair style)
• The simpler the character design, the more consistent your AI generations will be

Step 2: Create Your Character Reference (Saturday Morning)

Before generating any story illustrations, create a detailed character reference sheet. This is the single image that will anchor all your subsequent generations.

My Midjourney prompt for Maya: children's book illustration, young girl approximately 5 years old, curly auburn hair with two small braids, green eyes, wearing a yellow sundress with white collar, round face with freckles, friendly expression, simple clean illustration style, white background, character reference sheet

Generate 4–6 options. Select the one that best matches your vision. This becomes your "character bible" — the reference image for all future generations.

Using style reference: Save this image and use it with --sref [image URL] in all subsequent Midjourney prompts. This anchors the visual style and character appearance across generations.

Step 3: Generate Scene Illustrations (Saturday)

Work through your story page by page. For each spread:

1. Describe the scene in detail
2. Include your character reference (--sref)
3. Maintain consistent environment and art style descriptors across all prompts
4. Generate 3–4 options, select the best

Prompt template I used: children's book illustration, [scene description], [character description with key visual elements], warm watercolor style, soft colors, [time of day/lighting], --sref [character reference URL] --ar 4:3 --style raw

Example (spread 5): children's book illustration, young girl with curly auburn hair and yellow sundress sitting beside a large old oak tree with a sad expression, whispering to the tree trunk, golden afternoon light through leaves, warm watercolor style, soft colors, --sref [URL] --ar 4:3 --style raw

Dealing with Character Consistency Issues

AI consistency across a 14-spread book is imperfect. My strategies for maintaining consistency:

• Keep the character description in every prompt (don't abbreviate)
• Use the same --sref reference throughout
• If a character looks wrong in a generated image, regenerate until the character matches rather than accepting a near-miss
• Use Photoshop or Canva to make minor adjustments (adjust hair color, change dress color to match) on otherwise good compositions

By spread 14, I had accepted some variation in minor details (freckle density, exact hair arrangement) while maintaining the essential character: right age, curly auburn hair, yellow dress, round friendly face.

Cover Image

Generate the cover last — once you've developed a consistent character appearance. The cover should feature your best-looking character image with space for title text.

For text on the cover, I used Ideogram AI to generate the title treatment, since it handles text in images more accurately than Midjourney.

Step 4: Layout and Formatting (Sunday)

Tools for Layout

• Canva — easiest, good templates for book layout
• Adobe InDesign — professional, steeper learning curve
• Google Slides — surprisingly adequate for simple layouts
• Affinity Publisher — professional, one-time purchase

I used Canva. The book template library includes picture book formats.

Layout Process

1. Create a new Canva project with your book's target size (typically 8.5×8.5" for square picture books or 8.5×11" for landscape)
2. Create a spread template with image area and text area
3. Import each illustration
4. Add text for each spread in a clear, readable font (avoid overly decorative fonts for the main text)
5. Create front cover with title and author name
6. Create back cover with brief description and barcode placeholder

Typography Considerations

• Font size: minimum 18pt for body text (children's books are read aloud with the child looking at pictures)
• Avoid serif fonts for picture books — use clear sans-serif
• High contrast text on backgrounds — dark text on light, or light text on dark

Step 5: Print Preparation

For Print-on-Demand (Amazon KDP, Ingram Spark)

File specifications:

• PDF format
• 300 DPI resolution for all images
• CMYK color profile (KDP also accepts sRGB)
• Bleed: 0.125" on all sides that extend to the edge
• Interior margins: minimum 0.5" inner margin (for spine), 0.25" outer

Midjourney upscaled images are typically sufficient for 300 DPI at picture book size — the SDXL high-resolution upscale produces images suitable for up to 8×10" print without quality loss.

For Personal Printing (What I Did)

Export as PDF and order through a local print shop or an online service like Shutterfly, Snapfish, or Artifact Uprising for high-quality photo books. This is faster and cheaper for single copies.

My niece's book was printed at a local Staples for $18 with spiral binding. It's not a professional children's book — it's better in some ways, because it's the only one exactly like it.

Frequently Asked Questions

Can you use AI images to illustrate a children's book?

Yes. The main challenge is maintaining character consistency across multiple images. Use Midjourney's --sref parameter or Leonardo.ai's Image Guidance for the best results.

How do you keep characters consistent across AI images?

Use style reference (Midjourney --sref) with a strong character reference image. Include consistent character description in every prompt. Accept minor variations while maintaining key visual signatures.

Is AI-illustrated children's book publishing allowed on Amazon KDP?

Yes, with required disclosure of AI-generated content. Review current KDP policies before publishing as they continue to evolve.

How much does it cost?

Generation cost is minimal ($10–$30 for Midjourney monthly). Print-on-demand platforms have free basic access (Amazon KDP) or small setup fees (Ingram Spark).

Can you sell AI-illustrated children's books?

Yes — AI-illustrated books are selling on Amazon KDP and Etsy. Story quality, illustration consistency, and clear target audience matter most.

Final Thoughts

My niece has read her book forty times. That's the number I care about.

The process is genuinely achievable in a weekend if you write the story first and approach the illustration work systematically. The result won't be a Pixar film — it'll be something more personal: a story made for a specific child, with characters that feel familiar.

For a personal gift, the value isn't in the technical sophistication of the images. It's in the story existing at all.
