Kelly Fabric: Made of 10% linen and 90% polyester, lightweight 240 gsm. Color coordinated to match many styles. With a pleated effect on both sides as it rises to add a distinctive visual appeal, this design enhances the overall decor and gives the room an unmistakable sense of style and elegance. Inside Mount: Measure the inside width at the top of the window and provide us with your finished measurement. The factory will automatically deduct at least 3/8" from the headrail width (not the fabric) to ensure a proper fit. For height, use the exact window height or slightly taller. Minimum window depth is 2" (2 1/2" for motorized shades). If the depth is insufficient, please choose outside mount. Outside Mount: We provide additional side pieces of fabric at the top to hide the wood (Alum. Headrail without side cover). To avoid light gaps, measure your window frame's width and add 4 to 6 inches (2-3 inches on each side). For height, add 4 inches to your measurement. If you want to expose more of the window, please consider adding extra height. Custom Service: Each roman shade is made to order based on your exact measurements to ensure a proper fit.
