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.
