What are some creative ideas for replacing baseboard molding?

Consider replacing wood baseboards with simple MDF primed boards that are cheaper and easier to install than wood. Also, consider using several rows of thinner molding to create a completely unique baseboard.

To create custom baseboards using several rows of molding, start with the thickest piece of molding and install it first so it gives visual weight to the baseboard. Stack other thinner rows of molding on top to create a thicker baseboard. To add some color to the baseboards, allow a gap between the baseboard rows, and paint that gap a color that contrasts the baseboard and room paint. As an alternative to replacing the entire baseboard, also consider adding shoe molding to plain existing baseboards to add more architectural detail to the room.
