Metallic thread is a type of sewing thread that contains metallic fibers, giving it a shiny and reflective appearance. It is commonly used in embroidery, decorative stitching, and crafting to add a touch of glamour to fabrics. The thread can be made from various materials, including polyester or nylon, coated with a thin layer of metal, such as gold or silver. This thread is popular in fashion and home décor, often used in items like costumes, table runners, and ornaments. While it enhances the visual appeal of projects, metallic thread can be more challenging to work with than regular thread, as it may fray or break easily during sewing.
