Once the shade is within the canister, you end up with roughly 3 1/2 inches of stacking on a modern Roman shade. The longer the stacking on a typical Roman shade, the longer the window. It may be anywhere between 6 and 16 inches long. The thickness of the cloth is another feature of the contemporary Roman shade. The thicker the fabric, the more light-blocking power it will have. Today, Roman shades are available in a wide variety of colors and designs. As you can see, Roman shades are very versatile and useful window treatments that can fit any home decor. They provide protection from the sun while still letting in plenty of light. Their only drawback is that they cannot be used as a doorway into a room because they must remain inside their packaging. However, this limitation doesn't hinder their ability to add style to your home. If you want to learn more about Roman shades or buy one online, visit our website today!
