What is a "window tier"?

A window tier, also known as a tier curtain or café curtain, is a type of window treatment that covers only the lower portion of a window, leaving the upper part of the window exposed. Tiers typically come in sets of two and are hung from a rod or tension wire. They are commonly used in kitchens, bathrooms, and other areas where natural light is desired but privacy is still needed. Window tiers can be made from a variety of materials, including cotton, linen, or lace, and come in a range of styles and patterns, from simple and understated to more decorative and ornate. They are a popular choice for those looking to add a touch of charm and coziness to their home, and are an easy and affordable way to update the look of a room.
