I have a house that was built in 1930 and has all plaster walls. I
want to replace the trim on all of the walls since it has been painted
MANY times and no longer looks nice. I'm a little hesistant on pulling
the trim off of the walls since I have no idea what to expect behind
it. The trim now is about 6" high. Is it easy to remove the trim and
replace it? The walls are not exactly straight, so I worry that the
trim won't fit correctly. Do I need any special tools or equipment to
put up the trim?

Thanks.
