Probably the most economical binding method. Pages are folded, creased and stapled with two steel wires. This is often seen on booklets, magazines and brochures that have a smaller page count.
Using the same method as standard saddle stitched (stapled), coloured wire is either cast coated or plastic dipped to provide an attractive alternative to the normal stitches.
Opposite are examples of coloured saddle stitching using copper coated wire instead of the standard steel wire.
