How to Draw Mouths on Your Fashion Figures
Draw a simple mouth for children's faces.
Draw a circle for a kid’s face and add in the face grid. Sketch in some dashed horizontal lines that divide the lower half of the face into thirds. The opening of the mouth goes at the lower dashed line.
Draw the opening of the mouth as a pair of downward curves that meet at a dip in the middle. Draw the bottom of the lips as a slight upward curve.
Erase the face grid and your other guide lines.
