Draw a capital B with a black pen that is 2 pixels thick. The letter is 40 pixels wide and 80 pixels high. Use two half-circles to make its rounded parts.

The turtle starts in the center of the canvas, facing east. This is the bottom-left point of the letter.

1. Draw the left edge, 80 pixels up.
2. Draw across the top to (20, 80).
3. Face east. Draw a half-circle with radius 20 and turn 180 degrees to make the upper rounded part.
4. Draw to (0, 40). Lift the pen, move to (20, 40), and lower it again.
5. Face east. Draw another half-circle with radius 20 and turn 180 degrees to make the lower rounded part.
6. Draw to (0, 0) to finish the letter.
