Decorator Leslie Curtis joins Bob in the project house's parlor to discuss the room's wall treatments. In lieu of wallpaper, stencils are used to add a decorative touch to the interior walls�a decorating solution borrowed directly from early 19th century America. Artist Ken Forcier is on location to demonstrate the stenciling process, showing how the stencil patterns are laid out and applied to the wall before paint is brushed on. Bob takes a turn at the brush, applying paint to one of the laser-cut Mylar stencils supplied by MB Historic D�cor.

Bob talks with artist Margo Datz about decorative striping and stenciling in the Victorian Cottage master bedroom. She uses a template to insure the lines are the same distance from the ceiling along the wall. Margo provides a tip when using painter�s tape. She seals the tape to the wall with adhesive matt medium to prevent the paint from bleeding under the tape. She shows Bob how to add a stencil pattern to the painted wall trim.

Work continues on the parlor's wall stencils. Bob and Ken Forcier are applying the second "layer" of the stencil�an ochre hue to complement the first shade of blue. To aid in the vertical alignment of the stencil patterns, Vila crafts a makeshift plumb bob using a washer tied to the end of a thread and secures it to the wall with painter's tape. Another tip: Adding a small dog ear to a corner of the stencil makes it easier to peel the stencil from the wall after the paint has been applied.

Bob checks in with artist Polly Forcier from MB Historic Decor to get an update on some of the home's decorative painting. Forcier is working on a Colonial-style mural inspired by the work of Rufus Porter, an itinerant painter from the 19th century. Forcier has chosen the dining area just outside the sunroom as the location for her mural. The natural sunlight pouring through the windows serves as a reference point for the highlights in her mural. She uses charcoal to outline the mural's design and then begins painting. For the details, such as the scene's houses and trees, Forcier uses a series of nine stencil overlays. To apply the paint, Polly uses a special stenciling brush employing a rotating stroke rather than stippling the paint on.

In the sunroom, Bob appraises Polly Forcier's traditional Shaker-style landscape wall mural, giving it high marks for the Colonial-themed home. A final look at the walls in the parlor reveals more intricate stencil work. Artisan Ken Forcier has completed the application of a reproduction stencil pattern that was originally found in an early 19th-century Vermont farmhouse.

Bob tours the front vestibule, highlighting the beautiful stencil work done by Kim Sweet. The stencil work replaced moldings in many homes of this nineteenth century era. The stencil work is not just on the wall but extends to the ceiling. This small vestibule will take the artist four days to complete using oil based paint. Greg Rochlin meets with Bob to discuss a few architectural pieces that borrow modern technology, combine stock pieces to antiques to create an authentic paneled wall and inlayed flooring. Bob meets with Susanne Csongor and Christine Lane of CLC Interiors to discuss some of the choices made in decorating the dining room and front hall. They used dense busy patterned wallpaper in the small dining room to give it an intimate feel. Combining it with red cotton chintz drapes with goblet pleats to accent the berries in the wallpaper. A Russian rug on the floor in the hallway was the color palette inspiration for this room as well as a blue Greek turnkey pattern for the runner up the stairs.

Designer Leslie Curtis of Curtis Designs is back on location for a final tour of the Colonial-themed decor. Curtis points out the wall stencils from MB Historic Decor, which feature a folksy early American pattern. The furniture in the room includes historic reproductions of pieces found in antique homes, as well as original case pieces from the students of the North Bennet Street School of Boston, Mass. In the formal dining room, the Georgian-style table and Chippendale chair by craftsman Tommy MacDonald create an inspirational model for a classic interior.

Bob reviews how building or renovating a house can sometimes be an unhealthy proposition. Asthma, allergies, and other respiratory problems can often be attributed to manmade chemicals in the home. In West Palm Beach, Florida, the American Lung Association has sponsored a designer showhouse that highlights a healthy home. Bob reviews the rooms in the house, each of which is designed by selected interior designers and artists.

In his grand finale here in Malibu Beach, Bob and our designer, Robyn, take us on a tour of the finished California-Spanish dream house. We look at the media room, kitchen, and living/dining areas. In the media room she went with an ode to west theme. In the Kitchen it is both elegant and informal with its circular wall. Old Brazilian hand carved dining table ties it together. In the living room She pulled together pieces from all over to replicate looks of the Adamson house and other areas of Southern California. She used unbleached twill fabric on the sofas and a leather trunk from South America as the coffee table.

Bob visits with Suzanne from the National Trust for Historic Preservation at the breathtaking Lyndhurst mansion with over 40 rooms showcasing Victorian high living in New York's Hudson River Valley. In the front hall Suzanne shows off the faux marble walls, painted on plaster look exactly like marble tile. The home features a gothic dining room with plaster beams designed to look like oak and a marble fireplace. The picture gallery has a composite floor of Maple and Walnut dating back to the 1880s and a stained glass window of Tiffany glass called the Angel of the Arts.
