Step 4: Make it look pretty

I added some trim here and there.  Take note of where the door opens and that your trim doesn't hamper the doors movement.  This was a bit of trial an error for me.

Also in my case I mounted the trim to the center bookcase on one side and mounted it to the fixed bookcases on the other.  this really helps to conceal the shelf as well as providing the handle to open the door.
