Welcome to the Playhouse
Mr. McGroovy’s Box Rivets help you create the kinds of cardboard box castles you only dreamed of as a child. But what I really love are the detailed plans including a castle, throne, pirate ship or a fire engine. He even offers instructions on how to make Santa’s sleigh, which is a good way to get a holiday lawn decoration from reused materials. The site even offers tips on how to find free large appliance boxes, and how to fit eight refrigerator boxes in your car.
