packaging and flat patterns

so I am throwing out the boxes for a couple of large electronic devices. I am always hesitant, but after a while it just takes up too much space. So collapsing the boxes, i unload all of the packaging, and think about the people who design the cardboard compartments that will accommodate all of the big and little pieces that make up the vacuum cleaner, for example. And just like a garment this 2-d material becomes activated in a 3-d role.
