FABRIC & CORDLESS DESIGN: D23-01 crafted from high-quality 30% Reed and 70% Flax, 688gsm, this shade is a beautiful and eco-friendly addition to any room. The natural texture and warm tones of the material create a soothing atmosphere. The cordless lift design ensures safety and easy to open and close. All hardware included. SHADING PERFORMANCE: The natural material blocks out the harmful UV rays but allows natural light to enter the room, making you enjoy the art of light and shadow. If you need better shading performance, privacy cotton liner 60% and blackout liner 100% are provided for you to add. INSIDE MOUNT: Includes additional no-punch accessories. Measure the window opening width and height. Reduce the measured width by 3/8 inch to ensure it can be installed in, the height can be slightly greater than the measured height to avoid measurement errors creating a gap at the bottom, or the same as the measured height. Note there will be slight gaps on sides due to fabric deductions. Ensure your window depth is at least 2 and 3/4 inches. Otherwise, please choose outside mount. OUTSIDE MOUNT: Includes additional side pieces of fabric at the top to hide the wood. Measure the window frame width and height. Add the measured width by 2-6 inches, add the measured height by 5-8 inches to prevent light gaps on the sides of your window, then customize this size. NOTE: This roman shade is intended for indoor use, do not place it in moist, damp environments.
