Cardboard Lumber

Step 3Prepare the Cardboard

Prepare the Cardboard
I will be making a large solid block of cardboard with all the corrugations pointed the same way. If you want to make classic plywood, alternate the corrugations throughout the block. The second way could be stronger, but I'm going to make it this way because it looks nicer.

You have to cut your cardboard so that each single layer lays flat, and is completely filled with cardboard. The look and strength of your lumber will all depend on how well you cut your cardboard layers up. It would be best to have all cardboard meet at hard, squared off corners.

To prepare your raw cardboard boxes, you have to cut all of them into flat rectangles, removing all tape and anything you can to make them just cardboard rectangles.
