Paper City

I found these one day and they looked like so much fun. You print out the cities, vehicles and people. Decorate them or leave them black and white. Then, pretend and use your imagination. I found it worked best to print them on cardstock, so I could fold the buildings and they would stand up.

Set up took some time. Each person, vehicle and city needs to be cut out. He has created a lot of different things; helicopters, bikes, buses, roads & landscapes, Paris and Sydney. My guy enjoys flying around the city and crashing into buildings, but he is enjoying himself. Add legos and a shoebox (mountain) for more fun.
