It's not enough to keep up with the Joneses anymore. Homeowners, as well as home builders, are looking for that extra something to make their homes stand out. For many of them, the answer is in the trimmings?the interior trim details that turn basic rooms into jewel boxes. Homeowners are choosing elaborate decorative trim packages for their remodeled or custom homes. And buyers shopping for new homes gravitate to models that builders have dressed up with door and window casing, crown molding, chair rails, ceiling medallions and other elegant trim.
