Provide a visual link. "The wall covering for this dining room was selected to complement the adjacent living room and also to provide visual interest in lieu of painting the rooms the same or a similar color," says designer Michael Abrams. "The same wall covering was also used in the home's foyer. This treatment ties all three spaces together."He adds, "I encourage my clients to use wall covering to add tremendous depth and visual interest to a room. I mainly recommend textural wall covering, such as grass cloths, linens or silks, since they remain timeless. While wall coverings are more expensive than paint, they provide a huge impact and are worth the expense. And wall coverings used intermittently with paint create unexpected visual interest."
