I used them in the bathroom in the old house but now, they are in the foyer. You don’t need a window to soften a room with fabric. Six yards of fabric at $5 per yard {1502 fabrics, Thomasville, NC} is much less expensive than a 8′ x 5′ rug. Do you have a place that needs softening that could use some drapes–what about that opening to your dining room?
