Hi, I have a strange situation where a door opens INTO a small walk-in closet. It's of incredible poor design because you lose a lot of the space just inside the closet due to the door opening IN. What I want to do is re-hang the door so that the door swings OUT (freeing up more space inside the closet) instead of opening IN. Is this easy? I was told that I'd have to take off the entire door frame. I have no idea how difficult this might be. Is there a good resource (if it's easy) that I may consult for performing this?
