First, you'll add a shelf to the base of your nightstand. On each leg, measure 7 inches from the bottom and install an L-bracket. The L-brackets should face each other to provide a base for the shelf. Use the level to ensure they are mounted level.
Measure the depth between the front and back legs at this height to determine the depth for your shelf. Measure the width from the outside of the front legs and add 2 inches. This will determine the width for your shelf. Once you have these dimensions, cut the 3/4-inch-thick piece of wood to size. We used white oak.
