Choosing Thread Is About More Than Finding the Right Color

Walk into a sewing or quilting department and you may find dozens of thread types, fibers, weights and colors. They may look similar on the spool, but they can behave very differently once they pass through your sewing machine and into the fabric.

Thread is an important part of the finished project. The wrong combination of thread, needle, fabric and machine settings can contribute to thread breakage, poor tension, skipped stitches, excessive lint or disappointing stitch appearance.

The right thread should work with the fabric, the purpose of the stitch and the sewing machine. Thread used for piecing does not always need to have the same characteristics as thread selected for decorative quilting or embroidery.

At Brothers Sewing & Vacuum Center, we help customers with sewing machines, quilting fabric, thread and accessories. That allows us to look at the entire project rather than treating the thread as an isolated purchase.

Understanding Common Thread Types

There is no single thread that is best for every quilting project. Start by understanding the characteristics of the most common thread fibers.

1

Cotton Thread

Cotton thread is a traditional choice for quilting and is especially popular for piecing cotton quilting fabrics.

Quality cotton thread can provide smooth stitches and a natural appearance that blends well with cotton fabric.

Different cotton threads can vary considerably in smoothness, lint production, strength and consistency.

High-quality thread can reduce lint and provide more consistent stitching than inexpensive, uneven thread.
2

Polyester Thread

Polyester thread is strong, durable and available in many different weights and finishes.

It can be an excellent choice for piecing, quilting, garment sewing and many other projects depending on the specific thread.

Fine polyester thread can provide strength without adding excessive bulk to seams.

Do not judge thread only by fiber type. Construction and quality can be just as important.
3

Rayon Thread

Rayon is often selected for decorative stitching and embroidery because of its smooth appearance and attractive sheen.

It may not be the first choice for every structural seam, but it can produce beautiful decorative results.

Match the needle, machine speed and tension to the specific decorative thread you are using.
4

Specialty Threads

Metallic, variegated, decorative and other specialty threads can add texture, color changes and visual interest to quilting and embroidery.

These threads may require different needles, reduced machine speed or tension adjustments to produce the best results.

Test specialty thread on a fabric sample before stitching the finished quilt.

Why Thread Weight Matters

Thread thickness affects the appearance of your stitches, seam bulk, needle choice and how prominently quilting shows on the finished project.

Finer Thread

Fine thread can blend into fabric, reduce seam bulk and work well when you want the piecing or quilting stitches to be less noticeable.

Medium-Weight Thread

Medium-weight thread is versatile and can be useful for many general sewing, piecing and quilting applications.

Heavier Thread

Heavier thread makes stitching more visible and can become an intentional design element in decorative or machine quilting.

Choose Thread Based on the Job

The purpose of the stitching should help determine the thread you select.

Thread for Piecing

Piecing thread should create strong, consistent seams without adding unnecessary bulk. Smooth, quality cotton or fine polyester threads are common choices.

Thread for Machine Quilting

Machine quilting thread can either blend into the quilt or become part of the design. Consider the desired stitch visibility, fabric, batting and quilting pattern.

Thread for Embroidery

Machine embroidery often uses threads designed for smooth high-speed stitching and strong visual impact. Thread, stabilizer and needle selection all affect the finished result.

Match the Thread, Needle, Fabric and Sewing Machine

Thread does not work independently. A successful stitch depends on the relationship between the thread, needle, fabric, tension and sewing machine.

A heavier thread generally needs a needle with an eye large enough to allow the thread to pass smoothly. Delicate fabrics may require finer needles and thread. Specialty threads may require their own needle style or machine adjustments.

When changing thread types or weights, sew a test sample using the same fabric and batting as the actual project. Check both sides of the stitching before beginning the quilt.

If thread repeatedly breaks, loops, shreds or produces poor tension despite correct threading and needle selection, the problem may be with the sewing machine rather than the thread.

Brothers Sewing & Vacuum Center can help with thread selection, sewing supplies and professional sewing machine service when the machine itself needs attention.

Frequently Asked Questions About Quilting Thread

Common questions about choosing thread for piecing, quilting and machine sewing.

What type of thread is best for quilting?

There is no single best thread for every quilt. Cotton and polyester are both widely used. The best choice depends on whether you are piecing, machine quilting or creating decorative stitching.

What thread should I use for piecing a quilt?

Many quilters use a quality cotton or fine polyester thread that produces strong seams without excessive bulk.

Can I use polyester thread on cotton quilting fabric?

Yes. Quality polyester thread is commonly used with cotton fabric. Choose the thread according to the project, desired appearance and sewing performance.

Why does my quilting thread keep breaking?

Thread breakage can be caused by incorrect threading, a damaged or incorrect needle, excessive tension, poor-quality thread, machine speed or a problem within the sewing machine.

Should my quilting thread match my fabric?

Not necessarily. Matching thread can make stitches less visible, while contrasting thread can turn the quilting into an important part of the design.

Does thread weight affect the needle I should use?

Yes. Thread thickness is one factor in needle selection. The needle eye must allow the thread to move smoothly while the needle itself must also be appropriate for the fabric.

Do you carry quilting thread and sewing supplies?

Brothers Sewing & Vacuum Center carries quilting fabric, thread and sewing accessories and can help customers choose products for their sewing and quilting projects.
