Repurpose our sideboard (that's languishing in the garage) by redoing with paint and it becomes a centerpiece. I like the shelves above it, too.
Use wallpaper inserts trimmed with molding to dress up bland or dated cabinet fronts. To update a boring built-in, first apply colorful paint. Next add flair to the cabinet fronts by attaching decorative wallpaper in coordinating colors. Finish by framing the wallpaper inserts with painted molding and adding new hardware.
