Step 6: Now learn how to draw this Phineas and Ferb character's arm guides. Draw a line on each side of the body as guides for Candace's arms. The line on the left bends in the middle and moves down toward the bottom of the triangle. The line on the right curves up toward Candace Flynn's head. Draw a small circle at the end of each line as guides for her hands.

Step 7: Draw the guide for Candace's legs and feet under the body. The guide consists of a vertical line under the triangle that splits in two at the bottom, and then bends back up to form two small triangles.

Step 8: That’s it for the initial sketch! You have learned how to draw the basic shape of the Phineas and Ferb character Candace Flynn. 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 the circles in Candace's head for her eyes. Draw a small circle inside each eye as a guide for her pupils. Inside each, pupil draw an even smaller circle to represent glare. On the top edge of each eye, draw a small line for her eyelashes, and above each eye draw a small, curved line for Candace's eyebrows.

Step 10: Now learn how to draw this Phineas and Ferb character's nose and mouth. Draw a small angled line in between Candace's eyes where the construction lines meet for her nose. Use the sideways D shape as a guide to draw her mouth. Inside of the mouth, draw a line on the top for her teeth and a small curved line on the bottom for her tongue.
