Ristikkäissidonta

Ristikkäissidonta, which translates to "cross-binding" or "interlaced binding" in English, is a fundamental technique in bookbinding. It refers to a sewing method where the thread passes through the sections of a book block in a criss-cross pattern. This creates a strong and decorative spine, often visible on the exterior of the binding.

The core principle of ristikkäissidonta involves sewing stations, typically located along the fold of each section (signature) of the book. The thread is passed from one station to the next, looping around the previous stitch or a spine support like a cord or band. This creates a series of interlocking stitches that hold the sections together. The visual effect is a lattice-like pattern on the spine.

Different variations of ristikkäissidonta exist, depending on the number of sewing stations, the spacing of these stations, and the type of spine supports used. It can be a purely functional method for sturdy bindings, or it can be executed with decorative threads and precision to enhance the aesthetic appeal of the finished book. This technique is commonly found in historical and fine bindings, appreciated for its durability and visual interest. It is distinct from other sewing methods like kettle stitch binding or sewing on tapes.
