My three-year old son finds the basement parking lots in the malls interesting to watch. He can find huge number of real cars of different models and colours, all parked at one place; lined-up cars, winding roads and neatly drawn parking lines and indications. It is indeed an amusing sight for kids who play with toy cars.
We tried to make a cardboard parking lot to include in his play road mat. It is, perhaps, the most simple-to-make DIY toys I’ve ever done for him. In the pictures below, I’ve detailed easy steps to make a toy parking lot using cardboard and a few add-on road signs. If you are planning to make one for your toddler, this might be of some help.
