Step 4: Add the wood
The 4.5 inch trim left and right of the shelf-door, the right side is fixed to the fixed shelf, the left side moves with the door.I had to bevel notches in the trim on the right because the horizontal trim dives under it as the door opens. I also had to slightly round the horizontal pieces to slip underneath smoothly.
I am not the best woodworker, and the materials ( mdf and particle board ) are less than optimum, and the walls are crooked, but the results were great. Nobody would ever see the finished wall and think "Hey I wonder if that is a door?"
all in all i have about $350 in the project.
