Step 21 Adding the top of the door frame

Next, measure another piece of wood to create the top part of the door. To do this, hold a piece of wood at right angles to the tops of your two parallel door pieces. Mark the spots that will allow you to connect it to the "B" pieces of wood at the top of the pentagon. From the outside of the pentagon, use 3" screws to attach this piece where it fits against the top of the pentagon and the other door pieces.
