Step 6: Draw the guide for the hat on top of the Cat in the Hat's head. First draw the brim of the hat right on top of the head as a long, curved line. Then draw the top part as a kind of rectangular-shaped box that bends a bit in the middle. The height of the box should be about the same as the head and neck combined.

Step 7: That's it for the initial sketch! You have the basic shape of Dr. Seuss' Cat in the Hat. 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 8: Tighten the outer shape of the Cat in the Hat's eyes by making the lines thicker and darker. Draw a few lines around each eye for the eyelashes and extra detail.

Step 9: Inside each eye, draw a small dot for the Cat in the Hat's pupils. Above each eye, draw a thick curved line for the eyebrows. The line on the left should be shorter because of the perspective.

Step 10: Under the eyes, right where the construction lines intersect, draw the Cat in the Hat's nose. First draw an oval shape, then a small line under it. Draw a few lines within the shape of the nose for extra detail.
