Assuming you would like a tutorial on how to craft a door out of wood, here are the instructions:
First, you will need to cut your lumber down to the correct size. To do this, measure the opening of the door frame and add 1/2 inch to each side for clearance. Then, use a saw to cut the boards to these dimensions. You should have four boards in total - two for the top and bottom of the door, and two for the sides.
Next, lay the boards out on a flat surface and drill pocket holes into each end of them. These will be used to attach the pieces together later on.
Once all of your holes are drilled, it's time to start assembling the door! Begin by attaching the two side boards to either side of one of the top or bottom boards using wood glue and screws. Make sure that all joints are flush before moving on.
Repeat this process with the remaining top or bottom board until all four pieces are attached together in a rectangle shape. At this point you may want to sand down any rough edges or corners before moving onto staining or painting your door.
Now that your door is complete, you'll need to hang it in your doorway! Center the door in the opening and mark where each hinge will go with a pencil. Remove the door from its frame and predrill pilot holes for your hinges before screwing them into place (on boththe door andthe frame). Finally, rehang your new wooden door and enjoy!
