The prompt

Create a minimalist tattoo design in the continuous one-line drawing style. The subject is a sitting fox in side profile, rendered as a single unbroken black line that traces the entire silhouette — ears, snout, tail curl — without lifting from the paper. The line varies slightly in weight (thicker at curves, thinner at straight edges) to suggest form, but there is zero fill, zero shading, and zero color. The background is pure white. The overall composition is portrait-oriented, centered, with the fox occupying roughly 70% of the frame and generous white space surrounding it. The aesthetic should look like professional tattoo flash art ready to be traced by a tattoo artist. Do not add any decorative elements, flowers, or text.

Why it goes viral: The 'one-line' tattoo trend has sustained multi-year virality because the optical trick of a continuous stroke reads as magic — viewers stop scrolling to figure out where the line starts and ends.

How to use it

Paste the full prompt into ChatGPT (GPT-4o) in a new conversation.
Inspect the result: confirm the line is unbroken and there is no fill or grey shading.
If needed, reply: 'Regenerate with no fill and no shading, pure single black outline only.'
Download the image, place on a soft warm-white (#faf9f7) background, and post as a carousel with slide 2 showing a wrist placement mockup.

Pro tips

GPT-4o image generation follows detailed spatial instructions well — explicitly naming where the line should be thicker gives more realistic tattoo weight variation.
If the output adds shading, add 'absolutely no grey tones, no gradients, only a single black vector-style stroke' to your follow-up message.
Ask for a second variation with 'the line starting at the nose tip' to get a compositionally different result for A/B testing on Instagram.
