i think this project is the easiest of all. and frankly, who doesn't love paper doll - or in this case, paper car? well, certainly not my champ! i drew cars, ships, and airplanes on a piece of paper (preferably cardboard) and cut them all. he likes to pretend as if they were real :)
and if your kid is in his coloring stage like yuara, even better! he ended playing the paper cars by coloring them one at a time. i think it's safe to say that he had a good time!
