Double-Needle Coptic Stitch Blank Book

This handmade book is from a coptic binding class I took at the San Francisco Center for the book, called Double-Needle Coptic Stitch Blank Book. It was another fantastic bookbinding class! I really needed the practice on the technical aspects of bookbinding when I took this class, I've forgotten so much. And it was a really interesting stitch. I can't wait to explore it more. This book is about 6" x 5".
