I especially like using white, natural, grey or khaki for large pieces. These classic shades make an endlessly versatile backdrop. My customer, Kathy, had the same idea when she chose 12 oz. khaki denim for her sleeper sofa slipcover.
Now, she can layer her choice of accent colors throughout the living room without having to start over with an entirely new slipcover every time she wants to change out her decor.
