Step 1: Determine where you would like your shelves to be placed and the length of each shelf. Use painter's tape in approximately the same thickness as your shelves to get a feel for how the shelves will look in the area. This easy trick helps you visualize the spacing between the shelves.
Use a saw to cut your reclaimed wood to the correct length. I was able to keep the width of my boards as it. If you must adjust the width be sure to remove excess from the back leaving the front of the boards in raw form. This will make for a much more charming finished product.
