Coptic binding is a traditional bookbinding technique dating back to ancient Egypt, characterized by its exposed spine and the use of single sheets of paper or parchment sewn together with a distinctive Coptic stitch. Unlike modern bound books with folded signatures, Coptic binding employs individual sheets stacked and sewn in pairs, creating a chain-like pattern along the spine. This method enables the resulting books to open flat while displaying the elegant stitching along the spine. Coptic-bound books often feature a variety of cover materials and decorative elements, making them popular among artisans and book artists for their historical significance, aesthetic charm, and functional design, allowing for both functionality and artistic expression.
