Thread sewn brochures and books have a spine that is literally sewn together with thread, using a specially adapted version of a traditional Singer sewing machine!
Each section is collated and folded, then sewn together using thread to form a secure and robust bound brochure.
Threads sewn into the spine can either be hidden with a PUR-glued cover, or exposed to create a beautiful stitching pattern. Exposed thread binding is especially effective when using a thread colour which contrasts with the colour of the cover, as illustrated here.
