An invisible zipper is a type of zipper designed to be hidden from view when the garment is closed. It features a unique construction where the teeth are concealed behind the fabric, creating a seamless look. This makes it a popular choice for dresses, skirts, and other clothing items where aesthetics are important. To install an invisible zipper, a special foot is often used on a sewing machine, allowing for precise placement. These zippers come in various lengths and colors, making them versatile for different sewing projects. They provide a clean finish while still allowing for easy wear and removal of garments.
