These Powis Parker Fastback Headbands are designed to give your Fastback bound hard cover books the look of a stitched hard bound book. Headbands are the narrow pieces of striped or solid fabric at the top or bottom of each book block. Although headbands were once an integral part of the binding process but they are now purely decorative. Headbands are available in seven different colors and are packaged with 25 6" strips per package.
