Choosing Thread for Your Next Project

The right thread depends on your fabric, project, and sewing machine. Start with your pattern’s recommendations and your machine manual, then test your thread and needle combination on scraps of the actual fabric.

Cotton thread

A popular choice for piecing cotton quilts and sewing woven cotton fabrics. It’s also used for quilting when you want a soft, traditional appearance.

Polyester thread

A versatile choice for many sewing projects. Its strength and slight stretch can make it useful for garments, everyday sewing, and quilting. Choose a thread intended for your technique.

Embroidery thread

Designed for decorative stitching. Machine embroidery threads commonly come in polyester or rayon. Check the thread’s care instructions, especially for projects that will be washed frequently or exposed to bleach.

Metallic and specialty thread

Adds sparkle or texture to decorative work. These threads may need a specialty needle, slower stitching, and adjustments recommended by your machine or thread manufacturer.

Hand-quilting thread

Choose thread labeled for hand quilting. Some hand-quilting threads have a coating and should not be used in a sewing machine unless the manufacturer specifically allows it.

Understanding thread size

Thread labels can use different sizing systems. In many weight-based systems, a higher number indicates a finer thread; with Tex, a higher number indicates a thicker thread. Don’t compare numbers across different systems as though they mean the same thing.

Getting better results

Use a needle suited to both the thread and fabric. If you experience shredding, skipped stitches, or uneven tension, rethread the machine, check the needle, and test again before adjusting tension. Follow your machine’s guidance for bobbin thread and threading.

Before you buy

Check the thread’s fiber, size, spool format, intended use, and care instructions. Large cones may require a compatible thread stand.
