1. Draw the heads.
Draw two circles, one for each spy about two-thirds of the way up on your page, and about a third of the page from the left and right sides.
2. Add facial details.
Draw a hat brim at the top of each circle. Add eye holes, with a small arch and a long pointy line, on either side of the center. Draw a small square for the nose, and a wide curve for the mouth of each spy.
3. Draw the bodies.
For each spy, draw an isosceles triangle with its top about even with the eye holes and its base down the bottom of the page. Round off the outer edges of the triangle, and add notches for the hands near the middle of each side.
4. Add arms and hands.
Draw 3 pointy notches for fingers on each hand, and draw curved lines for the arms.
5. Add legs and feet.
Draw 2 notches for toes on each foot, and draw bent lines for the legs.
6. Add the trench coats and hats.
For each spy, draw a long curved line in front of the body for the trench coat. Draw a triangle, with the bottom even with the eyes and the top pointing outward, for the lapels of the coat. Draw a wide brimmed hat for each spy.
7. Add the finishing touches.
Give one of the spies a gun, and the other one a knife. You could also add other objects, such as briefcases or binoculars, to make the scene more interesting.
8. Color your spies.
Traditionally, one spy can be black, and the other spy may be white or another color.
