What are some cool things that you've found made of paper, or a woodpulp type product, that is more like paper than cardboard?

My wife and I collect handmade paper paintings. The two largest are 3 foot by 4 foot. Got those at a hotel closing, they were in the lobby. They are a landscape scene with trees and hills.

I saw this the other day and can’t wait to try it!

I am always fascinated by the way people come up with folding cardboard boxes to make them stronger or start from a flat piece, and then fold here and fold there, like magic, it becomes a box.
