As the next step in door fabrication, I decided to mock up the door card and build stuff the will be behind it. Using cardboard, two different styles were mocked up. One with a door pocket and the other without.
I liked the clean look of the one without the door pocket but decided the other was more practical. It will give a place to store stuff and with this placement alleviates the need for a visible door pull. The door frame tubes will pass through near the top of the pocket and will work nicely as a grip to pull the door shut.
I then went about mocking up the pocket box again using cardboard. While using the door frame as a pull simplifies in one way, it makes for a very complicated interior box requiring separate pieces to go around the frame tubes.
