I reversed the doors to my bedroom (they're small "french" doors I guess but they don't have glass or open to the outside like normal french doors) so they open out instead of in (the room is small despite the big door opening).
After reversing the door swing and hanging the new door, the gap between the doors is different at the top than at bottom. I know that means something isn't level but I checked it with my four foot level before I attached the door frame and everything was fine.
Any tips to hanging interior doors? It looks so easy on TV!
