Over the years I have featured quite a few pieces of cardboard furniture on Grassrootsmodern. It's because the base material is free, and with a little creativity and some DIY motivation you can actually make some pretty good looking stuff. If you've ever thought it would be cool to make something out of cardboard, but you've never really known where to start, you're in luck! I was browsing through Instructables and I saw this nice little tutorial on how to make a cardboard bench. The same ideas will apply to basically any cardboard furniture, all you need is 1) A Saw 2) Lots of cardboard 3) Glue... lots of glue.
