[AI Library] Chapter 21. Goods and POD
Nano Banana Pro Practical Prompt Book
Part 6: Making Money with Nano Banana
Chapter 21. Goods and POD
Kim Kyung-jin
POD stands for Print On Demand. It means "printing when an order comes in." In the past, to make t-shirts or mugs, you had to make hundreds in advance and store them in a warehouse. If they didn't sell, you took a big loss. However, with the POD method, the product is made and sent one by one when a customer orders. There is no worry about inventory, and no initial investment cost is needed. You just need to upload AI images made with Nano Banana Pro to a POD platform. If someone likes the design and orders it, the platform company handles manufacturing and shipping. You just need to create good designs.
Guide to Selling on Amazon Merch and Redbubble
What is Amazon Merch (Amazon Merch on Demand)?
Amazon Merch is a POD service operated by Amazon, the world's largest online store. When you upload a design, Amazon customers worldwide can buy t-shirts with that design. Amazon handles everything: printing, packaging, shipping, and customer service. You upload the design and receive royalties (commission) every time it sells.
Amazon Merch royalties are usually between 15% and 30% of the sale price. If a $20 t-shirt sells, about $3 to $6 goes into your account. If 100 shirts sell in a month, that's $300 to $600, or about 400,000 to 800,000 won.
B. How to Join Amazon Merch
Not everyone can join Amazon Merch right away. You must submit an application and get approval. It can take anywhere from a few weeks to several months to get approved. Attaching a simple portfolio when applying increases your chances of approval.
Application steps:
Go to merch.amazon.com
Click "Request Invitation"
Log in with your Amazon account (or create a new one)
Enter your information in the application
Briefly explain what kind of designs you plan to upload
Submit a portfolio link if you have one
Wait for the approval email
Once approved, you can only upload 10 designs at first. This is the "Tier System." If sales go well, your limit increases to 25, 100, and 500 designs. As your tier rises, you can apply designs to more product types (phone cases, cushions, etc.).
C. How to Join Redbubble
Unlike Amazon Merch, Redbubble is easy to join. You can upload designs right after signing up. Redbubble allows you to apply designs to over 100 types of products, including stickers, posters, laptop skins, blankets, and tote bags, as well as t-shirts.
Redbubble signup steps:
Go to redbubble.com
Click "Sell your art"
Sign up with your email address
Set up your profile
Upload a design via "Add new work"
Adjust the design position and size for each product
Set your own margin (profit rate)
The advantage of Redbubble is that artists can set their own margins. The default margin is 20%, but you can raise it to 30% or 40%. However, higher prices can reduce sales, so you must find the right balance.
D. Creating POD Designs with Nano Banana Pro
For designs to upload to POD, PNG files with a transparent background are recommended. A resolution of at least 300 DPI and a size of 4500×5400 pixels or more is ideal.
Example prompt for a character design for t-shirts: A cute cartoon cat wearing a chef hat, holding a spatula, simple flat illustration style, bold outlines, vibrant colors, white background, suitable for t-shirt print, vector art style, no shading, clean design A cute cartoon cat wearing a chef hat and holding a spatula, simple flat illustration style, bold outlines, vivid colors, white background, suitable for t-shirt printing, vector art style, no shadows, clean design.
Cute food character prompt for stickers: Kawaii style pizza slice with cute face, big sparkly eyes, small blush on cheeks, tiny arms and legs, pastel colors, white outline, sticker design, die-cut ready, transparent background, chibi food character
Design prompt with an inspiring quote: Typography design with text "Stay Curious" in retro style font, surrounded by hand-drawn stars and planets, vintage color palette, navy blue and gold, distressed texture effect, suitable for merchandise print
E. Comparison by Platform and Selection Criteria
Item | Amazon Merch | Redbubble / Registration Difficulty: Approval Required (Hard) | Instant (Easy) / Product Types: Approx. 10 | 100+ / Profit Margin: 15-30% | 20-40% (Self-set) / Customer Base: Very Large | Large / Shipping Speed: Fast (Prime available) | Normal / Competition Level: Very High | High
Since 2024, Redbubble has introduced a "tier system." New accounts have limited exposure. You must consistently upload high-quality designs and build a sales history to move up to the "Premium" or "Artisan" tiers. Reaching these tiers allows your work to appear higher in search results.
2. Building AI Character IP and Licensing
A. What is IP?
IP stands for Intellectual Property. Simply put, it refers to the characters, names, and stories you create. Kakao Friends' "Ryan," LINE Friends' "Brown," and Sanrio's "Hello Kitty" are all examples of IP. These characters are used for dolls, stationery, clothing, and even hotels and airplanes. A company that owns an IP grants permission for other companies to use it in exchange for payment. This is called "licensing."
As of 2024, the global character licensing market is valued at $19.8 billion (approx. 26 trillion KRW). It is projected to grow to $33.6 billion (approx. 45 trillion KRW) by 2033. Using Nano Banana Pro, you can create your own character IP.
B. Creating Character IP with AI
A single cute image isn't enough to become an IP. A character needs a name, personality, and backstory. People must be able to connect with it emotionally.
Character Design Checklist:
Name: A name that is easy to remember and say
Appearance: Features recognizable at a glance
Personality: A clear personality (energetic, shy, quirky, etc.)
Backstory: Where they came from and what they like
Worldview: The setting of the world where the character lives
Character sheet generation prompt example: Character sheet of "Mochi" the round white bunny, multiple poses and expressions: happy, sad, surprised, sleepy, angry, eating, running, sitting. Consistent design across all poses, simple cute style, pastel pink accents, small round body, long floppy ears, tiny dot eyes, small pink nose, reference sheet layout, white background Character Sheet: Round white bunny "Mochi," various poses and expressions: happy, sad, surprised, sleepy, angry, eating, running, sitting. Consistent design across all poses, simple cute style, pastel pink accents, small round body, long floppy ears, tiny dot eyes, small pink nose, reference sheet layout, white background
Character series prompt with a setting: A cozy bakery scene in a fantasy village, the main character is a small brown bear named "Benny" wearing a baker apron, surrounded by magical floating bread and pastries, warm golden lighting, storybook illustration style, soft watercolor texture, other animal villagers visible through the window
C. Maintaining Character Consistency
The strength of Nano Banana Pro is character consistency. You can draw the same character identically across various scenes. This is crucial for building an IP. If the character looks different every time, people won't remember it.
Drawing various situations with a consistent character: First, create a base character image. Attach that image and make a request like this: Please draw this character at the beach holding a surfboard while keeping them exactly as they are. Maintain the character's face, colors, and proportions exactly the same. Keep this exact character design and draw them holding a surfboard at the beach. Maintain the same face, colors, and proportions exactly.
Creating seasonal versions: A scene where this character is wearing winter clothes (red scarf, earmuffs) and drinking cocoa against a snowy background. Do not change the character itself; only add the clothes and background.
D. Licensing Basics
If your character becomes popular, other companies might want to use it. This is when you enter into a licensing agreement.
Types of Licensing:
Merchandising License: Using characters for dolls, stationery, clothing, etc.
Advertising License: Featuring the character in advertisements
Entertainment License: Using the character in animations or games
Licensing Revenue Structure: When you sign a licensing agreement, you typically receive payment in two ways. The first is an "Advance," which is money paid upfront when the contract is signed. The second is a "Royalty," which is a certain percentage (usually 5-15%) of sales every time a product is sold.
E. Starting an IP Business on a Small Scale
It is difficult to aim for large-scale licensing from the start. Start on a small scale.
Post characters consistently on social media
Build a fanbase
Start with stickers and emojis
Expand into goods if the response is positive
As your fanbase grows, companies will contact you first
The 2025 goods market trends are "emotional animal characters" and "universe-linked characters." Characters with personalities and stories beyond just being cute are popular. Characters with unique appearances created with AI tools are also getting attention.
3. Automating T-shirt, Phone Case, and Sticker Design
A. Design specifications by POD product
Each product requires different image sizes and formats. It is best to create images with the correct aspect ratio from the start when using Nano Banana Pro.
Recommended specifications by major product: Product / Recommended Size (pixels) / Ratio / File Format | T-shirt: 4500 × 5400, 5:6, PNG (transparent background) | Sticker: 2800 × 2800, 1:1, PNG (transparent background) | Phone case: 1242 × 2688, approx. 9:19, PNG/JPG | Mug: 4500 × 1400, approx. 3:1, PNG (transparent background) | Tote bag: 4500 × 4500, 1:1, PNG (transparent background) | Poster: 6000 × 8000, 3:4, JPG/PNG
B. Mass Producing T-shirt Designs
It is efficient to create several variations from one concept. For example, if you make a "coffee-loving animal" series, you can produce them by changing only the animal in the same composition.
Series design prompt examples:
Base template: A cute [animal] drinking coffee from an oversized mug, relaxed expression, simple cartoon style, bold black outlines, limited color palette (3-4 colors), text below saying "But First, Coffee", vintage t-shirt design aesthetic, distressed texture, transparent background
Variation 1 - Cat: A cute cat drinking coffee from an oversized mug, relaxed expression, simple cartoon style, bold black outlines, limited color palette (orange, cream, brown, black), text below saying "But First, Coffee", vintage t-shirt design aesthetic, distressed texture, transparent background
Variation 2 - Bear: A cute bear drinking coffee from an oversized mug, sleepy expression, simple cartoon style, bold black outlines, limited color palette (brown, cream, tan, black), text below saying "But First, Coffee", vintage t-shirt design aesthetic, distressed texture, transparent background
Variation 3 - Owl: A cute owl drinking coffee from an oversized mug, wide awake expression, simple cartoon style, bold black outlines, limited color palette (gray, cream, gold, black), text below saying "But First, Coffee", vintage t-shirt design aesthetic, distressed texture, transparent background
C. Phone Case Design
Phone cases are vertically long. You must consider the camera hole position when designing. Place important elements in the center or at the bottom.
Pattern design prompt for phone cases: Seamless pattern of small cute cats and fish, kawaii style, pastel colors (pink, mint, lavender), white background, repeating tile pattern, suitable for phone case, small elements evenly distributed, playful and whimsical mood
Illustration design prompt for phone cases: Vertical composition illustration of a dreamy night sky with a crescent moon, a small house on a hill, fireflies glowing, stars scattered, deep blue and purple gradient background, soft glow effects, phone case design, magical atmosphere, studio ghibli inspired style
D. Sticker Design
Stickers are one of the best-selling products in POD. Because the price is low, there are many impulse purchases, and many customers buy multiple copies of the same design.
Die-cut sticker prompt: Die-cut sticker design of a happy avocado character, kawaii face with sparkly eyes, tiny arms waving, speech bubble saying "Holy Guacamole!", thick white border around character, vibrant green colors, cute food illustration, transparent background, ready for sticker cutting
Sticker pack (set) design: Sticker sheet with 8 different plant-themed characters: happy cactus, sleepy succulent, excited monstera, shy fern, dancing sunflower, grumpy mushroom, peaceful bonsai, energetic venus flytrap. Each character in a small circle frame, consistent kawaii style, pastel green color scheme, white background, ready for sticker pack
E. Batch Production Workflow
You need a system to efficiently create 10 or 20 designs a day.
Efficient design production sequence:
Select Theme (10 minutes): Decide on the theme for today's series
Write Base Prompt (5 minutes): Create a template prompt
Generate Prompt Variations (10 minutes): Create 10 variations from the base prompt
Generate Images (30 minutes): Generate each variation using Nano Banana Pro
Selection (10 minutes): Choose the best images
Post-processing (20 minutes): Remove backgrounds, resize, and more
Upload (15 minutes): Upload to the POD platform
Using ChatGPT for automated prompt generation: Ask ChatGPT or Claude to create prompts in bulk. "Create 10 t-shirt design prompts for an 'Animals Drinking Coffee' series. Each animal should be different, in a vintage style with a transparent background. Write them in English."
4. Naver Smart Store Goods Shop Management Know-how
A. What is Smart Store?
Smart Store is an online shopping mall platform operated by Naver. Individuals can also open a shop for free. Products are exposed to many customers through Naver Shopping search. There is no separate monthly fee besides the sales commission, which reduces the burden. Unlike Amazon or Redbubble, you must prepare the products yourself on Smart Store. While the POD method is possible, you need to order from manufacturers to maintain inventory or collaborate with consignment production companies.
B. How to Open a Smart Store
Opening Process:
Access the Naver Smart Store Center (sell.smartstore.naver.com)
Sign up as a seller
Select seller type (Individual/Business)
Decide on store name and URL
Enter business information and settlement account
Connect Naver Shopping and Naver TalkTalk
Register products
Initially, you can start as an individual seller without a business registration certificate. It is recommended to register the business as sales increase.
C. How to Produce Goods
There are several ways to turn designs made with Nano Banana Pro into actual products.
Method 1: Use POD companies. Use domestic POD services such as MarppleShop, Today's Goods, and Tumblbug Goods. Once you upload the design, they manufacture and ship it when an order is placed.
Method 2: Use small-batch manufacturers. Outsource items like stickers, acrylic keyrings, and memo pads to small-batch manufacturers. Searching for "goods production" will reveal many companies. The minimum order quantity is usually 50-100 pieces.
Method 3: Mass production and maintaining inventory. If you are confident it will sell, produce in bulk. The production cost per unit decreases as the quantity increases.
D. Optimizing Product Registration
There are several points to ensure products are easily searchable on Smart Store.
How to write product names: Good example: "Cute Cat Sticker Waterproof Laptop Deco Sticker Pack 20 Types" Bad example: "Cat Sticker" Include words that customers are likely to search for in the product name. Include related keywords such as "waterproof," "laptop," "deco," and "character."
Product image specifications: Create the representative image as a square of 1000×1000 pixels or more. The first image is the most important. The product must be clearly visible.
Creating product images with Nano Banana Pro: Product photo of cute character stickers arranged on a white marble background, aesthetic flat lay style, soft natural lighting, some stickers applied on a laptop visible in the corner, lifestyle product photography, clean and bright mood.
E. Goods Shop Operation Strategy
1. Preparing Seasonal Products: Prepare cherry blossom themes for spring, sea themes for summer, maple leaf themes for autumn, and Christmas themes for winter. Products should be uploaded at least one month before the season. Seasonal product design prompts: Spring season: Cute cherry blossom themed sticker design, a small bunny character sitting under a sakura tree, falling pink petals, soft pastel colors, spring atmosphere, kawaii style, transparent background. Winter season: Christmas themed character design, a penguin wearing a red Santa hat and scarf, holding a wrapped gift box, snowflakes falling, festive mood, cute illustration style, suitable for merchandise.
2. Set Product Composition: Bundle 5 stickers, 3 postcards, and 1 memo pad into a "Set" for sale. Offering a slight discount compared to individual purchases increases the average transaction value.
3. Running Limited Editions: Operating limited editions such as "Sale this month only" or "Limited to 100 units" encourages purchases. Launch new designs once the limited edition ends.
4. Review Management: Providing a small service (like extra stickers) to first-time customers increases the chance of receiving good reviews. More positive reviews improve search rankings.
5. Maintaining Brand Aesthetic: Unify the atmosphere of all products. Match the tone across packaging, thank-you cards, and store banners. The 2025 trend favors "places with a brand aesthetic" over "places that just sell."
F. Real Success Stories
In 2024, Jobkorea and Albamon began selling goods for their brand character "Dreams Crew" on Naver Smart Store. They introduced various products such as golf driver covers, slippers, doll keyrings, and blankets. They created an emotional connection by embedding the message "supporting your dreams" into the character. The clothing brand Hazzys sold out its 2024 F/W season sweaters using the AI-generated character "Hary." Subsequently, in the 2025 S/S season, sales of character products increased by 320% compared to the previous year. This is an example where AI image generation technology led to actual commercial success.
G. POD and Smart Store Integration Strategy
Ideal operation model:
Test phase: Test first with POD platforms like Redbubble and MarpleShop
Check response: Identify which designs sell well
Mass production: Produce only the well-selling designs in bulk
Smart Store sales: Maintain inventory and sell on Smart Store
Brand building: Continuously expand with the same character IP
This way, you can increase profitability while reducing inventory risk because you only mass-produce designs proven through POD.
