How do you mark out an oval?

To mark out an oval, you can use a simple method involving two pegs and a string. First, drive two pegs into the ground at the desired distance apart, which will serve as the foci of the oval. Then, tie a length of string to the pegs, ensuring it is longer than the distance between them. By keeping the string taut and using a stick or pencil, you can trace the outline of the oval shape around the pegs.
