DMC Machine Embroidery Thread is a highly mercerized cotton thread made for clean machine embroidery, applique, and decorative stitching. Each spool holds 500 m (547 yd) in Colour 604 and is offered as a fine Size 50 thread for smooth fills, outlines, and quilting details. Because the dyes are colourfast, it suits washable projects; follow the care needs of your base fabric when laundering, ironing, or dry cleaning.
