Curtain tape, also known as curtain header tape or curtain rod pocket tape, is a type of fabric strip used to create a pocket at the top of a curtain. This pocket is designed to slide easily onto a curtain rod, allowing the curtain to be hung and adjusted with ease. Curtain tape is typically made from a durable material such as polyester or cotton, and it comes in various widths to accommodate different curtain rod sizes. It is an essential component for making custom curtains, as it provides a professional finish and ensures the curtains hang smoothly and remain in place.
