Create a detailed, descriptive prompt that establishes your main character and the story's mood. Include specific details about character appearance, setting, lighting, atmosphere, and artistic style. For children's books, clarity and warmth are essential elements to communicate through your prompt.

Use this structure as a model: "a small, friendly cat named Milo with a tiny backpack, standing at a quiet bus stop at night, glowing moon above, fireflies floating, warm, magical children's book illustration, soft watercolor style, cozy atmosphere." This prompt includes character details (small cat, friendly, named Milo, tiny backpack), setting (quiet bus stop at night), atmospheric elements (glowing moon, fireflies), and artistic direction (warm, magical, soft watercolor style, cozy atmosphere).

Type your prompt into the Midjourney interface. Combine concrete visual details with emotional tone descriptors—include the art medium (watercolor, digital painting, pencil sketch) and mood words (cozy, warm, magical, dreamy) to guide Midjourney's interpretation. Submit your prompt and wait for generation to complete within 30-60 seconds, which will display four variations of your prompt interpretation.

When your generated results load, examine all four image variations carefully. Identify one image that best captures the visual style you want to maintain throughout your entire book—this selection is critical because it will serve as your style anchor for all subsequent illustrations.

Prioritize images that display colors, textures, and shapes aligned with your story's overall vibe. For children's books, focus on soft edges, warm lighting, and friendly facial expressions that create an inviting, age-appropriate aesthetic resonating with young readers.

Consider technical aspects like composition balance, color harmony, and character proportions. The reference you choose will guide Midjourney's interpretation of every subsequent prompt. This careful selection process ensures your entire book feels cohesive rather than appearing as disconnected illustrations.

Click on the style option or style reference feature associated with your chosen image. This action instructs Midjourney to treat this specific image as a visual guide for future generations by analyzing its artistic qualities, color palette, rendering style, and compositional approaches.

Applying a style reference maintains visual consistency across multiple prompts—particularly crucial for children's book illustration where readers expect a unified artistic vision. Without this consistency, your book would appear disjointed and unprofessional.

The style reference doesn't copy your image exactly but rather extracts its aesthetic qualities, which then influence how Midjourney interprets new prompts while still allowing for different characters, settings, and actions. This balance between consistency and flexibility makes the style reference feature powerful for sequential storytelling.

Write your second prompt to advance the narrative while maintaining the established visual style. Introduce a new story element while keeping character and atmosphere consistent. For example: "a whimsical glowing bus made of moonlight arriving, friendly round windows, sparkling dust, Milo stepping aboard, dreamy night colors, gentle cartoon style, enchanting children's illustration."

Notice how this prompt maintains character continuity (Milo) while introducing new elements (the magical bus). Descriptive phrases like "dreamy night colors" and "gentle cartoon style" echo the atmospheric qualities from your first prompt, helping reinforce the visual consistency created by your style reference.

Click Submit to generate images that follow both your chosen style reference and the new narrative elements. The results should feel like a natural progression from your first illustration. Midjourney will process your prompt through the lens of your style reference, and generated images should maintain the same color temperature, rendering approach, and artistic qualities as your first scene.

2:02

Continue building your story world by crafting a third prompt that deepens the narrative. For an interior scene, type: "inside the magical moon bus, floating stars, fluffy seats, smiling creatures of the night, Milo looking amazed, dreamy pastel colors, warm, glowing children's book style." This prompt shifts perspective to show the interior environment while maintaining character presence.

Maintain consistent prompt structure with your previous attempts. Include setting details (inside the magical moon bus, floating stars, fluffy seats), additional characters (smiling creatures of the night), emotional content (Milo looking amazed), and artistic direction (dreamy pastel colors, warm, glowing children's book style). This structural consistency helps maintain visual consistency in output.

Submit this third prompt and wait for generation to complete. You should now have three distinct scenes that connect visually through shared artistic style and color palette. Review all three generations together to assess visual continuity—they should share similar line quality, color saturation, lighting approaches, and character rendering styles, forming a cohesive foundation for your children's book.

When satisfied with your generated scenes, prepare to download the images for book layout use. Click on each image you want to use and select the download option. Save each illustration at the highest available resolution to ensure your final book pages remain crisp and professional-looking.

High-resolution downloads are critical for print quality if you plan to create physical copies. Even for digital-only books, higher resolution prevents pixelation when viewed on different screen sizes. Midjourney typically offers several resolution options, so always choose the maximum available.

Organize your downloaded files with clear, sequential naming conventions—consider naming them "scene_01," "scene_02," "scene_03," or using descriptive names like "milo_at_bus_stop," "magic_bus_arriving," and "inside_moon_bus." This organization streamlines your layout process in the next phase and saves significant time during the design phase.

Navigate to Canva and create a new document for your children's book project. Choose or create a document size appropriate for your intended format—common children's book dimensions include 8×10 inches, 8.5×11 inches, or square formats like 8×8 inches. Consider your distribution plans (print-on-demand, traditional publishing, or digital only) when selecting dimensions.

Canva provides templates specifically designed for children's books that include proper margin settings and page layouts. If you're planning to print through services like Amazon KDP or IngramSpark, verify their specific dimension and margin requirements before beginning your layout.

Set up your document with multiple pages corresponding to the number of scenes you've generated. Most children's picture books range from 24 to 32 pages including front matter and back matter. For this tutorial, focus on creating spreads (two-page layouts) that showcase your illustrations with accompanying text.

2:46

Import your downloaded Midjourney illustrations into Canva by clicking the upload button and selecting your saved image files. Once uploaded, these images will appear in your uploads folder and can be dragged onto your document pages. Arrange them in the sequential order that tells your story effectively.

Place each illustration thoughtfully within your page layout. Consider whether images should be full-bleed (extending to the page edges), framed with white space, or positioned to leave room for text. Children's books often use full-bleed illustrations for maximum visual impact, but text readability should always remain a priority.

Ensure your images maintain their quality and don't appear stretched or pixelated. Review the flow from page to page to ensure your visual narrative progresses smoothly. The arrangement should guide young readers naturally through the story, making visual sequencing as important as individual illustration quality.

2:51

Add your story text to each page using a large, readable font appropriate for your target age group. Children's books require significantly larger text than adult books—generally 16-24 points for early readers. Choose clean, sans-serif fonts like Arial, Century Gothic, or specialty children's book fonts that prioritize legibility over decorative elements.

Apply generous spacing between lines (leading) to prevent text from appearing cramped. Young readers benefit from extra white space that helps their eyes track from word to word. Maintain wide margins around all text to prevent important words from being cut off during printing—most print-on-demand services require at least 0.25-0.5 inch margins, but children's books often benefit from even wider margins.

2:56

Use the same color palette for titles, headings, and accent elements that appears in your Midjourney illustrations. Use Canva's eyedropper tool to sample colors directly from your illustrations, ensuring perfect color matching. Apply these colors to text elements, decorative borders, page numbers, or other design accents throughout your book.

Consistency in color application creates a polished, professionally designed appearance. Consider color psychology and readability when selecting text colors—while matching your illustration palette creates cohesion, ensure sufficient contrast between text and background for easy reading. Dark text on light backgrounds or light text on dark backgrounds typically works best for children's books.

3:02

Review your entire book layout page by page to catch any formatting issues, typos, or design inconsistencies. Check that images are properly aligned, text is readable, margins are adequate, and the overall flow feels professional. This final review is your opportunity to polish before export.

Click Canva's export or download button when everything looks correct. Choose your file format based on your distribution plans—PDF is standard for print publishing, while PNG or JPG may work for digital-only distribution. Select high-quality or print-quality export settings to maintain your illustration resolution.

Download the file to your computer and review the exported version, as formatting that looks correct in Canva's editor sometimes appears different in the exported file. Your completed children's book file is now ready to share, publish through print-on-demand services, or distribute digitally.
