There are a few things you need before starting to draw a bumper car. First, you will need a piece of paper that is at least twice the size of your bumper car. Second, you will need some basic drawing tools. These include a pencil, paper, and ruler. Third, you will need to create the basic shape of your bumper car. This can be something simple such as an oval or a rectangle. Fourth, you will want to add the details of your car. This can be things such as headlights or taillights. Fifth, finally, you will want to add the color and design of your bumper car. This can be something simple like blue or red and white stripes or something more complex like a black and yellow design. Once all of these details are added, it is time to start drawing the cars!
