Soft subjects, and harder to color than they look. Baby skin has almost no shadow to hide behind, so the grayscale does the work for you: the modelling around cheeks, hands and closed eyes is already there before you pick up a pencil.
The collection mixes real babies — the “It's a Boy” and “It's a Girl” announcements people print for showers and cards — with fantasy infants: a baby fairy, a baby elf.
They are a favourite for new-parent gifts, because a colored page in a frame is a present nobody else brings.
