For human characters, focus on proportion and style: choose amigurumi safety eyes that suit the head diameter and define the expression with colour (black for a classic look, lighter tones for a softer gaze). Place the eyes slightly lower for a childlike effect, or a few millimetres higher for more “adult” features. A subtle safety nose (oval/small) works well for humans; centre it on the axis and adjust the eye spacing until the face “breathes”. Always test the placement on the surface before fixing.
For animals, prioritise amigurumi muzzles (oval or triangular) that define the species without overpowering the eyes. Combine them with amigurumi whiskers designed for safety noses (slots/holes), inserting the whiskers before closing so they are locked in place and won’t pull out. Adjust the eye distance to emphasise character: closer together = cute; further apart = mischievous. If the toy will be handled by children, avoid very small pieces or add extra internal anchors. With these well-proportioned amigurumi accessories, the face will read clearly and consistently both in photos and in hand.
