You don’t have to go through the trouble of redesigning stuff made from old materials such as cardboard. For all you know, the design may just already be in front of you.
Such can be seen with these recycled cardboard pendant lamps, making use of existing advertising cardboard.
EnjoyTwice was able to turn these supposedly hard to recycle materials, all made with plastic and glue.
Each light is unique and made in Amsterdam with the utmost care and attention. Their design process was led by the intrinsic merits of the material.
