Businesses in the sewing threads category supply thread for joining, repairing and embellishing fabric and other materials. Their ranges commonly include polyester, cotton, nylon and silk threads, as well as blends and specialist options such as embroidery, quilting, overlocking and heavy-duty thread. Products may be available in different weights, colours and spool sizes, with choices suited to hand sewing, domestic sewing machines or industrial equipment. Some suppliers also provide related sewing essentials, including needles, bobbins, sewing machine accessories and notions such as zips or fastenings. Customers may be able to browse colour charts, select thread for particular fabrics or projects, and obtain guidance on thread weight, fibre and compatibility with a machine. Businesses may serve home sewists, dressmakers, textile and craft workers, manufacturers, or repair and upholstery services.
