Step 6: Inside the rectangle, draw a vertical line and a horizontal line as construction lines. The vertical line should be closer to the left and the horizontal line closer to the bottom.
Step 7: On the right side of the rectangle, right above the horizontal construction line, draw a curved line similar to a letter U with a horizontal line inside as a guide for Stewie Griffin's arm. Draw another horizontal line near the bottom of the rectangle to help you place Stewie's feet.
Step 8: That's it for the initial sketch! You have the basic Stewie Griffin shape, so now go in and tighten your drawing. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.
Step 9: Darken Stewie's eyes, and inside each draw two horizontal lines for Stewie's upper and lower eyelids. Draw a small circle inside each eye for his pupils. Above each eye, draw an angled line for Stewie's eyebrows.
Step 10: Below the area where the construction lines meet, draw an angled line similar to a "less than" sign <. Below Stewie's nose, draw a curved line that looks like and arrow pointing left for Stewie's mouth.
