Sewing Zips & Zippers

Open-ended zips separate completely at the bottom pin box, allowing the two sides of the zip tape to pull apart entirely—making them essential for jackets, coats, cardigans, and hoodies. Closed-end zips remain permanently joined at the bottom stop, making them the standard choice for dress side seams, skirt back closures, trouser flies, cushion covers, and bags.

An invisible (concealed) zip features teeth curved backwards onto the underside of the zip tape. When stitched into a garment seam using an Invisible Zip Foot, the stitching runs right next to the teeth coil, leaving only the tiny teardrop pull slider visible on the outside of your fabric for a completely invisible, professional finish.

Standard adult denim jeans typically require a 5-inch (13cm) heavy-duty metal jeans zip featuring brass or nickel teeth. Metal jeans zips are specially constructed with flat auto-lock sliders and extra-strong teeth designed to handle high seam tension and repeated heavy laundering without bursting.

Yes! If the zip teeth are undamaged but the slider has pulled off, snapped, or stopped interlocking the teeth, you can use a Zip Fix Replacement Slider. These universal sliders clip directly over the existing zip teeth chain, restoring full zip function instantly without needing to unpick seams or stitch a brand-new zip into your garment.
