Blackout Drapes are done by adding a Blackout Lining to any fabric. Our Blackout Lining is a 3 pass Blackout Lining made of Cotton and Acrylic. The Blackout lining is great for not only Blacking out a room but also great for Insulation.
Side Note: The Black Dots on the Stitching happens from the Blackout Lining. Blackout Linings are made from Cotton and Acrylic. As the Drapes are being stitched, the sewing needle is hot and causes the Acrylic to show in light color fabrics. Unfortunately, there is nothing we can do to stop this from happening.
