Coats & Clark's Professional Machine Embroidery is the ideal thread to use when embroidering. This 40-weight thread has a lustrous sheen for embellishing items with decorative stitching or embroidery. It is made of trilobal polyester and can be used for digitized designs on embroidery and conventional sewing machines. The 4000-yard, high-volume spool equals 6.5 conventional spools, which means fewer starts and stops when embroidering a design. Coats & Clark's Professional Machine Embroidery Thread is machine-washable/dryable and colorfast even when using bleach. Choose from 12 colors.
