Andy McGrew, aka Mr. McGroovy, gave us a heads-up about his brilliant site (Mr. McGroovy’s Box Rivets) in which he explains how to transform refrigerator cartons into amazing creations.
I have a “commercial website” (I call it a microbusiness, my wife calls it a black hole) with free plans for building various projects out of refrigerator boxes. To help pay for the site I sell little plastic fasteners that make it easy to build with cardboard. I’ve been working on the illustrated plans for some time now, and the ideas are easily adaptable. I also have a few pages on the importance of play.
