I started by making a card pattern. The sides and back were one-piece and the base was shaped to fit. We taped the two side parts where it needed to fit around the base. After cutting out the sides, we made a card wedge to give it more tilt in the back, about 5 degrees. We then mounted it all on a flat piece of wood and made the front higher than the back to find out whether it was too tall or too narrow to fit the space we had available.
