I worked on doors today... The bathroom door is made from three layers (middle is illustration board and the outer edges are kleenex box to create a paneled look. The front entry door has five layers: two kleenex box layers, middle illustration board (where the plexiglass goes) and two more kleenex box). The whole thing is painted to look like dark walnut. I still need to do the letterbox, doorknob and knocker, but I need to go buy some gold paint.
