Step 11: Use the original P shape as a guide to draw Candace's head. Follow the path of the P and draw the line at the bottom wider to create her neck. Leave a gap on the top left corner where her hair will be.
Step 12: In the next three steps, learn how to draw this Phineas and Ferb characters arms and shirt. Draw Candace's arm on the left using the line and circle as guides. Follow the path of the line and thicken up the shape for her arm. Draw a few curved lines at the bottom of the circle for her curled-up fingers and another curved line on the left for her thumb.
Step 13: Use the top part of the big triangle as a guide to draw Candace's shirt. Draw a curved line around the neck for the collar of the shirt. The bottom of the shirt should be near the middle of the triangle.
Step 14: Draw the arm on the right side by using the initial line as a guide. Follow the path of the line as you make Candace's arm thicker. Draw a few curved lines at the top of the circle for her fingers and thumb.
Step 15: Now learn how to draw this Phineas and Ferb character's hair. Candace Flynn's hair is a bit tricky, so it's divided into two parts. First draw the top and left side of the hair by following the path of her head. The line starts close to the right eye, moves up and to the left, then bends back down toward the left arm and finally curves up a bit to create a small point.
