For all of you kid-loving DIY-ers out there, Nicola Enrico Stäubli, a Swiss-based architect (and bike messenger), has created a line of free children’s furniture called Foldschool. The catch: you have to build it yourself using cardboard, some simple implements, and Nicola’s printable instructions. The first thing you think of when you hear the phrase “cardboard furniture” is probably “unstable” or “ugly,” but it appears that Foldschool is neither of those things. While its not furniture I’d furnish my house with, I think it would be fun to build with kids to show them that they can build (or help build) something tangible and usable in their own lives. And when you and the kids are done with the piece, you can snap a photo of it and send it to Nicola and he’ll upload it to the website for all to see.
