Adding in endleaves from Powis Parker's Fastback collection will add a sense of sophistication to your finished documents. They are specifically designed for use inside the front and back covers of your Fastback hard covers. These Endleaves come in sets (one for the front and one for the back) and are bound with the contents of your book. And when you go to finish the hard cover case, you use the hard cover guide to adhere the leaf into the front and the back of your case. The result is a finished hard bound book that looks highly professional.
