In a basement hobby room or office, turn one wall into an oversize message board. This treatment works in for basements where humidity and moisture are not a problem. And this treatment helps reduce noise and echoing. Staple batting and fabric to the wall before installing the baseboard and crown molding. Stretch wide ribbon on the diagonal from floor to ceiling to make diamonds. At each intersection of diagonals, hammer in a decorative furniture tack to create a tufted look.
