I often use the words paper boards and cardboards to mean the same thing. With any piece of cardboard furniture you need to start with a sketch. You don't need to be precise with the drawing. It's only to help you plan the construction so the furniture fits where you want it to fit. I write notes on my sketch to help me remember measurements too. For this piece I did a sketch of an overhead view to remind myself that it should have an area underneath for a person's legs just like a table would.
