Draw a capital F with a black pen that is 2 pixels thick. The letter is 40 pixels wide and 80 pixels high.

The turtle starts at the center of the canvas, facing east. This is the bottom-left point of the letter. Draw from here.

1. Turn left and move forward 80 pixels to draw the left edge.
2. Turn right and move forward 40 pixels to draw the top bar.
3. Lift the pen and move backward 40 pixels. Turn right and move forward 40 pixels.
