I split a pallet in half and added the extra racks to make the shelf. I then measured the notches and used a 1" bit to drill a hole and sawed out the rest of the notches with a jigsaw. I did a heavy sand puttied some problem areas to fine tune the shape. After that, i resanded and painted it with grey chalk finish spray paint. Once that I dried I used a white spray paint and blended the two colors to give a more whitewashed rustic look.
