The COSTUMAKERS Invisible Closed End Zipper 55cm (22") - Bordeaux - 1780 offers an ultra-discreet closure for garments demanding a seamless finish. Featuring an invisible #2.5 nylon coil set into ultra-lightweight tape, it remains hidden when closed, providing a clean line for dresses, skirts, and tailored trousers. To install, use an invisible zipper foot and baste lightly to confirm placement, then stitch as close to the coil as possible to maintain concealment. Once sewn, zip and unzip fully to ensure smooth function, and press carefully with a protective cloth to avoid heat damage. Coordinate with your fabric for a perfect colour match, and stock multiple lengths and hues to support varied design palettes. Always trim excess tape, grade seam allowances, and press each step for professional results.
