I Tried Creating Characters with ChatGPT
Hello, I'm Mikan.
I previously wrote an article about the process from creating to selling stickers, but
this time I'd like to delve deeper into the creation process.
This is my first paid article, but if you're interested, please
give it a read.
My LINE sticker sales application was approved and they are now on sale.
It took nearly two weeks from starting the creation to submitting the application.
It was tough! 💦
I thought it would go much smoother.
The reason I thought about making LINE stickers in the first place was
because I saw a video on YouTube saying, "You can easily make them with AI and Canva!"
Many people on note also write about selling LINE stickers, so I simply thought, maybe I can do it too.
I figured I couldn't talk about it without having something to sell, so
I started making stickers right away.
Let's just try making them for now!
First, I registered for Canva, which is supposedly easy to use.
Since it can be used online, it's very casual and easy.
At first, I thought about using Canva's image generation, but... um, what kind of illustrations of what?...
Oh no, the "make stickers" part ran ahead of me, and
I hadn't even thought about "making stickers of what" 💦
In the video I used as a reference, they researched popular animals with AI and, based on that research,
generated images in Canva to create them.
They were also using Canva Sheets (spreadsheets) to create text in bulk at the same time as creating the images,
but I was so focused on creating the characters that
the talk about text didn't sink in at all 💦
I later realized the importance of Canva Sheets, but my rough and careless personality of "just skip the words and methods I don't understand!"
caused even more
confusion (lol).
Back to the topic, creating the characters to use for the stickers.
From here on is the content of character creation with ChatGPT.
First of all, I've been with ChatGPT for about two months now.
I recently learned that talking with ChatGPT is called "bouncing ideas off a wall."
Now, where should I start the conversation?
Actually, before I thought about making stickers, I was thinking about
researching "LINE situations with mom friends" while bouncing ideas off ChatGPT to see if I could
reflect it on Instagram, but
when I have trouble with LINE messages with mom friends, it's "how to respond appropriately."If I had a set of stickers that I could send without making the other person feel anxious or distrustful,
I thought they would be easy to use.
So, I decided to create a character targeting "mom friends!"
I instructed ChatGPT with the setting, "You are the number one LINE sticker seller for women in Japan."
Then it said,
"If we're going with that premise, let's be a bit realistic.
"If we go with the 'mindset of the person who sells the most in Japan,' the first thing you absolutely don't do is use 'copyright-gray materials.'"
In other words 👇
👉 Don't even consider Picrew from the start (it's highly likely to be a waste of time)."
It's thinking based on "selling," not just creating characters ✨
ChatGPT is smart (I'm impressed).
From there, it offered even more concrete suggestions.

🔥 The premise of what successful people do
People who are strong with stickers for women generally do this 👇
✔ Completely original character
✔ Simple and conveys meaning at a glance
✔ Specialized for "everyday conversation"
✔ Narrow down the target (this is super important)
💡 The best-selling genre for women
Given the current trend, the target is👇
👩 For moms / Considerate style
Good work today
I'm sorry💦
Thank you✨
I'll contact you later
👉 Polite + soft language is strong
🎨 The correct pattern for a character
The best-selling structure is almost always this👇
Loose female character (simple face)
Big expressions (laughing, troubled, flustered)
Gentle colors (beige, muted tones)
👉 "Looseness" wins over heavy illustrations
Yeah, I can imagine using this myself
If I give instructions for a more specific character image from here
🎯 Concept
Gentle stickers you can use in mom-friend group chats without worrying
🎨 Character design (feel free to use as is)
Woman in her 30s to 40s
Loose hand-drawn style (round face, simple eyes)
Hair: Bob or ponytail
Colors: Muted beige, pink
Expressions: Large (laughing, troubled, flustered, heartwarming)
👉 Name (optional): Yuru-Mama-chan
Yeah, I can imagine it somehow.
Now, let's go generate some images based on this proposal!
The prompt I thought of based on this (a word I learned recently too) is
loose hand-drawn style woman in her 30s character, round face, bob hair, simple lines, gentle expression, muted colors, minimal detail, white background, LINE sticker style, full body, with margins
Based on this, I changed the [gentle expression] to [big smile] for smiling,
to [troubled expression, 💦 mark] for when she's flustered, and
to [hands together, sorry expression] for when she's apologizing.
I also generated variations with different hand motions (raising one hand, both hands in fists in front, one hand making an OK sign, etc.).

Now, it's finally time for Canva to shine!
Next time, I'll talk about creating stickers in Canva. Please wait a little longer...
