Use a level as a guide to measure and cut plywood that will become the decorative cover for the face of the bed box. Cut the 1 x 2s that will frame the front of the bookcases, as well as two longer pieces for the top and bottom. Use the shorter pieces to connect the two long ones.
Cut boards to create three "faux" doors. Three panels for the doors should be cut from 1/4" plywood.
To prepare the door pieces for assembly, use a tongue and groove cutter on the router. The blades will create a groove down the center of all four pieces of each door frame, as well as creative a decorative profile on the face of the 1 x 2 board at the same time.
Add glue to the ends of the one of the short boards and insert the tongue into the grooves of the longer pieces. Use a clamp to secure them. Stand the frame up and slide the 1/4" plywood panel into the grooves. Glue the ends of the final piece and slide it over the end of the plywood panel to adjoin the rest of the frame. Add a second clamp to the other end.
Add 1-1/4" screws to hold it in place and re-position the footboard. Use the 1 x 2 to align the footboard for the doors. Clamp the 1 x 2 even with the top of the cabinet doors, and slide each "faux" door up to the 1 x 2 and nail in place.
