Here are the steps to make an original shelf, like Valérie Damidot and her team. 01 - To make an original shelf, we start by tracing the location of the holes on the boards. 02 - Drill holes large enough to let the chains pass. 03 - Then slide the chains into the holes. 04 - Determine the distance between each board according to the number of links. 05 - Drive a screw into the field of each board, making sure that it crosses the chosen link and thus keeps the shelves at the right level. 06 - Repeat the operation according to the number of shelves. 07 - It only remains to hang everything on the ceiling and you get a nice shelf.
