💬 Frequently Asked Questions

Do I need to know how to draw?

You follow the printed number-to-mark guide rather than sketch a picture freehand. Use the warm-up section to get comfortable with the six marks before starting a page.

Which pen should I use?

Choose a black pen with a tip you can comfortably control within the cells. Try it in the pen-test section first to check the line and overall appearance.

Do I color every square solid black?

No. Each code has its own mark. Only code 5 calls for a filled square. The other marks create different densities that help form the image.

Can I complete a page over several sessions?

Yes. Complete a section, pause when you like, and continue with the remaining cells later.

Are the interiors different between covers?

Please check the details of your chosen edition. The cover design alone does not confirm whether the interior content differs.
