## Keeping your child recognisable

Flat shapes simplify the face, so we hold hair, skin tone and a signature colour steady to keep your child recognisable. That is the whole point of Once Books: you pick Minimalist flat once and it is locked to the book, so your child is the same child from the cover to the last page. See [how it works](https://www.oncebooks.com/how-it-works/), or browse [all the art styles](https://www.oncebooks.com/styles/).
