Rose Granada - Basswood Plantation Shutters Stained ‘Black Walnut’ ; From start to finish this DIY project was simple and straight forward. We measured our windows and sent these through online. Hubby installed the shutters and two years on we still love our gorgeous Shutters. In our theatre room we decided on a custom made colour 'black walnut'. I was quite impressed with the pricing not being a standard colour. So happy with this look also and the quality as usual is exceptional.
