Backboard for bookcase
I have been assembling bookcases to use as a base. I then connect and add wood trim. I am not happy with the "backboard that came with these shelving units. It is cardboard laminate that has been folded,creased and with perforations for cords - ugly. I want to add a wood grain material And then custom stain to match the finish and wood trim. But need something thin it needs to cover a 30" x 70" area. What is the best material to use?
