A-Door-Able

I still have more cleaning/polishing to do...but the door knobs are going to be great. The other style of knob (closets, inner doors) are brass with a copper back plate. I've learned something about doors in old houses..they get a bad rap.
I've heard a variety of complaints about how they are hard to close or open, and how annoying they can be. My experience is that after 20 - 30 coats of paint, a "lip" develops on the edges of the door. You may be suprised how much easier they open if you sand/strip/plane off that lip.
Additionally, I've found that many doors that don't seem to close properly have inappropriate screws in the hinges. In earlier times, people used what they had on hand whether it was a good fit or not. Check yours out, you may find that you're one .15 cent screw away from a door that closes and opens just fine.
