Roller blinds are made with two pieces of fabric, which both have alternating panels/bands: one solid color band followed by one sheer band. When the bands on both pieces of fabric are matched together, you get the look of horizontal blinds when open, including an outside view and natural light filtering into the room. To prevent light from entering and increase privacy, simply rotate the fabric so the solid colour bands fill the entire shade, giving the look of a traditional roller shade. Roller blinds are a top-selling and sheer shade choice which complements any décor. SPECIFICATIONS MaterialsAluminum Polyester Dimensions24 x 84
