Ta-da!her site. In her own words:
This little kitchen unit is built entirely from recycled (as in, salvaged from the dumpster) corrugated cardboard covered in contact paper. No glue, no nails, nothing but clever joining cuts make the kitchen entirely disassemblable so it can be packed flat for moving/storage. The structure is all my own design. (Can you tell I'm pretty proud of this?)
As she should be! Fortunately, Anna's ingenuity is everyone's gain. She's made the full plans available for sale for only $8 in her Etsy shop, forty-two roads.
