Cardboard Lumber

Step 4 Stack the Cardboard

Before you glue everything together, stack the cardboard in a neat pile. It's okay if there's a couple little gaps, we're just making sure we have enough. I wanted to make a 4'x4' square of cardboard the thickness of how deep my saw could cut.

Now is a good time to estimate the sq. ft. of cardboard and see how much you can build.
