Many bamboo patterns are open weaves, that allow warm, natural light into your room. However, open patterns do not offer a high degree of privacy. With the Platinum collection you can choose from three coordinating colors of privacy liner, which will still allow some light in, but provide complete privacy. And our liners are always stitched to your shade, so no glues or tapes which can degrade and discolor over time. Black out liners eliminate light through the shade and offer maximum insulation. With the Platinum Collection you can choose from three colors, all white or neutral to the street. Our attached liners are always stitched to your shade, so no glues or tapes which can degrade and discolor over time. You can also choose movable liners. This offers you two shades in one - a bamboo shade in front and a separate liner shade behind, which operates independently. This means you can raise the liner during the day for natural light through your shade and lower it at night for privacy. Shades with movable liners come on a wider, 2 1/2 inch headrail and have two sets of cords - one for each shade.
