Have you been to Paper Museum? We stumbled across this fun Japanese site and are now completely addicted. The site offers absolutely free pdf downloads that you can print yourself. Cut out the objects and assemble into a bakery, a kitchen, a candy store, etc.
Or how about this fun kitchen?
You can even put together this nifty little bento box.
Check out Paper Museum's site for many many more fun projects.
