Crown molding made of polystyrene foam has several advantages.

The polystyrene molding used in this project was provided by Creative Crown Molding.  You can click here to go to their website.

For this project, I did cut miters on the corners.  However, you can eliminate the need to do that by using these corner blocks also available from Creative Crown Molding and other suppliers.

This molding came in eight foot sections which means it can be conveniently shipped.
