Make it yours

The recipe is the style, not the picture. Put your own subject in and the highlighted part of the prompt changes.

Prompt

A naive single line doodle of a cat making a heart shape with its paws, drawn in one uniform weight black line on plain white. Wobbly hand drawn quality rather than smooth vector curves, no shading, no fill, no texture, minimal detail: two dot eyes and a simple mouth. Off centre on the page with generous white space. Charming and slightly clumsy.

The prompt gets you close. Feed one of the examples in as a style reference for the rest. Download the images

Tips

1Wobbly rather than smooth is the instruction that stops it becoming a clean vector icon.
2Give a stroke budget. "Drawn in about ten strokes" produces real restraint.
3Off centre placement reads as hand drawn. Perfect centring reads as software.
