This is a tutorial on making a dos-à-dos book by recycling a thin junk cardboard box (dos-à-dos means back-to-back). In the video, you'll see how a cardboard box that has four sides the same size will make a triple-book in one. To make a double-book, just take away one side. To make more than a triple-book, add more boxes to the mix. They're great, fun homemade journals!
