Your walls are bare and you want to adorn them. The best way is to add some pallet shelves that will make a pretty wall as well as giving you storage space. For the bracket shelves, you will need both bottoms of the pallet. Cut them and inspect them. Take the bracket shelves and sand them well especially the edges that you sawed. Once you are satisfied with the sanding, stain them a few times so that you are able to get a dark hue. Make a couple or more as they look better than a single isolated shelf. Put them up using strong holders and put candles, jars, a plant in a water bottle or anything that takes your fancy.
