This lamp is completely made with cardboard. I designed it thinking about the effect that only corrugated board can give.
It's basically composed of two parts. One is the base of the lamp that contains the lamp holder and light bulb, made bending cardboard to create a little box. The other one is a structure made with many strips of cardboard glued together in squares that create bigger squares and then a cube.
All you need is corrugated cardboard and patience, but if you enjoy creating as much as I do, you will actually enjoy the whole process!
I published the instructions to make my lamp on Instructables.
