To make this lamp you have to take a slab of wood and drill four holes with some distance so that the cheese graters can easily be suspended with gaps. Then take bulbs with holders inside each grater and take out their wires from their top to be connected to the main cord.
Then pass the four cords of graters from the wooden slab’s holes and connect all the four cords to the main cord with connectors.
Hang the slab with hooks and rope with care and your lamp is ready. This lamp can be ideal for a kitchen as it is made my recycling one of the kitchen utensils.
