Step 1: Tools and Materials
Pencil w/ eraser
Cardboard (Depending on a custom size, you should get a large box)
Small & Medium Size Paper Clips
It would be good to have extras of some of these materials in case you mess up.
Step 2: Making the Door/Table
I thought of adding the back layer of the door to make it complete in thickness, I realized that is a bad thing to do. So before you add the back of the door, MAKE SURE THE LOCK IS SECURED INTO THE DOOR BEFORE YOU PUT ON THE BACK!!!
The Lock I shall explain in a later step. But before the next step, tape up three edges of the door. The fourth edge will be for the top side.
