I used scrap 1/2 plywood for all of the sides of the box. I cut down a 2x2 into  3/4" sticks to reinforce the intersections and the hinge. These intersections were glued and nailed with a 16 gauge 3/4" finish nail. I added 1x4 strapping to give this box a shipping create look. I was carefull to adjust the back strapping to provide a rest for the hinge when open.
