Cardboard is actually just paper. It's a different color than what we consider to be paper. And it's a bit thicker than your average printer paper.

But it is just paper. And we can take a cardboard box apart and separate it into it's paper constituents - and turn that into a sketch pad.

In this video tutorial I don't just tell you how to do it. I actually do it. You can watch me make a sketch book out of a cardboard box.
