• Get a breakfast cereal box. • Cut it up. • Make a sketch of what each side of the trailer will look like. • Using a pencil, draw the outline shape on one of the sides of the box. • Remember that one side won’t have a door (a few caravans did have doors both sides, but most don’t). • Use the bare, unprinted side of the cardboard for the outside. • This is easier to draw on and paint sticks to it much better because the primer soaks in and seals it as well. • Once you’ve got the outline of one side of the caravan, use it as a template, and draw round it on the other piece of cardboard so you’ll have the other side of the caravan. • Mark out where the window holes need to be cut, and door for whichever side it’s going on. Most have the door on what would be the passenger side of a car. Decide if you want an opening door or not. For a ‘pretend’ one, score out the shape using an empty ballpoint pen. The same pen can also be used to make any rivet marks (as you’d have on an old caravan). •
