Went over to the trim store today. The choice is amazing! Basically we had to decide what shape we wanted for the trim as well as the size. We decided to go with medium weight of trim.
The cost of trim depends on the grade (paint or stain), the heaviness, and the complexity of the piece.
We decided to put crown molding on the lower floor, no crown moldings on the upper floor (the ceiling really doesn't support it), chair rails in the dining room and pilasters around the columns in the dining room, kitchen, and study.
