indivisible

Indivisible zippers are fixed zippers that cannot be opened in two halves - ideal if you want your project to remain closed at one end. In this category you will find a selection of indivisible zippers in different lengths, colors and tooth thicknesses, suitable for many sewing ideas.

What are inseparable zippers suitable for?

Indivisible zippers are often used in garments such as skirts or dresses, but they are also practical for pants, cushions, upholstery and flat bags. They ensure a clean look and reliable hold because the fastener cannot be pulled apart at the bottom.

Processing tips

• Use a zipper foot on your sewing machine for even sewing.
• Baste or tack the zipper in place before sewing to prevent it from slipping.
• For fine fabrics, I recommend using interfacing or interfacing at the zipper seam for more stability.
• Depending on the material, some zippers can be shortened or fixed with a zipper stop; check this before cutting.
• Finishing seams and topstitching give the zipper a professional finish.

Selection criteria & quality

When buying, make sure you choose the right length, the right tooth thickness and a color that blends harmoniously into the project. The quality of the slider and the finish at the end of the zipper affect the longevity - high-quality models are easier to sewing and last longer. More robust teeth are useful for heavy fabrics, finer versions for fine fabrics.
