The COSTUMAKERS Denim Closed End Zipper 20cm (8") - Rail - 1710 is designed for durability and style in denim garments. Featuring #3 brass metal teeth paired with lightweight tape, this closed-end zipper provides secure fastening for jeans, skirts, and tailored pants. To install, reinforce the fabric with interfacing or stay tape, baste the zipper in place to ensure precise alignment, and sew using a sturdy zipper foot. Finish with a topstitch to accentuate the seam line and integrate the zipper into your garment's aesthetic. Always test the zipper through its full range to guarantee smooth operation, then press with a protective cloth to set the stitches and protect the metal teeth. Maintain a stocked variety of lengths and colours to suit every denim wash and design specification, trim excess tape neatly, and press thoroughly for a polished finish.
