A few years ago, the Walker Art Center featured the Terra chair in a show of contemporary design. Organic in form and composition, it looked like a great project for my parents' 80-acre plot in Wisconsin. My visions of sprouting armchairs in unexpected places—overlooking the creek, beside their Chartres-style mowed labyrinth, along the intersecting paths through the woods—deteriorated when I saw the plans for the chairs (which involved simple interlocking cardboard sheets that are filled with dirt) were selling in the museum shop for $150.
Enter: ReadyMade magazine's plans for a sod couch. Way cheaper, do-it-yourself, and infinitely modifiable.
