Cordonnet 30 is a strong, smooth cotton thread traditionally used for buttonholes and topstitching. Its thickness and even twist make it well suited for decorative bookbinding work and hand sewing.

This thread works especially well for:
• Hand-sewn endbands
• Decorative and exposed stitching
• Light to medium bookbinding
• Journal and sketchbook sewing

It passes easily through sewing holes, holds tension well, and creates a visible, tidy stitch. The range of available colours makes it ideal for adding contrast or design detail to handmade books.

Cordonnet 30 is thicker than standard sewing thread and has a firm, even twist. This makes it ideal for endband sewing because it forms clear, defined stitches that sit neatly against the spine without sinking into the paper.

Its smooth surface allows it to glide easily around the core and through the sewing holes without fraying. This makes it easier to keep consistent tension while sewing the endband, which is important for both appearance and durability.

Because it comes in a wide range of colours, it is also excellent for decorative endbands. You can match or contrast the thread with your book cloth, paper, or cover design, turning the endband into a design feature instead of just a structural one.

Why it also works for sewing signatures

For light to medium books, this thread is also suitable for sewing signatures. It is:
• Strong enough for everyday journals and notebooks
• Thick enough to be easy to see while sewing
• Smooth enough to pass through holes cleanly
• Less intimidating for beginners than linen

This makes it a good option for:
• Journals and sketchbooks
• Decorative bindings
• Exposed spine sewing
• Practice bindings
• Endband practice

It gives a neat, visible stitch and is easier to handle than very fine thread.

A versatile thread for bookbinders who want colour, control, and decorative impact in their work.
