what is the proper way to install base molding on walls that are rounded at doorways and closet entrances. I just bought my first house. it was built in the 50's and has plaster walls. the house has hardwood floors and no base molding, not even shoe or quarter round! the corners of the walls are square, but it is rounded in the doorways. I'm not sure how to install the molding correctly in this scenario. I guessing you cut the molding at the same angle as the curve??? also the is a rounded metal plate running vertically along every entrance way at the rounded corners? any ideas???
