Buying Guide: Choosing the Right Needles for Your Brother GX37

Not all needles are created equal, and using the wrong type can damage your fabric or your machine. Here are the key factors to consider when selecting needles for your GX37.

Needle Size and Fabric Weight

The most critical factor is matching the needle size to your fabric. A finer needle (like 65/9 or 75/11) is perfect for lightweight materials such as silk, chiffon, or satin, preventing snags and visible holes. For medium-weight fabrics like quilting cotton or linen, a 90/14 is a versatile go-to.

When you move to heavier materials like denim, canvas, or upholstery fabric, you need a larger needle (100/16 or 110/18) that can penetrate the dense weave without bending or breaking. Using a too-small needle on heavy fabric often leads to skipped stitches and needle breakage, a common frustration we’ve seen in our best sewing machine for general use guide.

Needle Type and Compatibility

Most home sewing machines, including the Brother GX37, use a standard HAx-1 needle system. This means you have a wide range of compatible needles, but you should always verify the system before purchasing. The universal needles we reviewed are HAx-1, so they fit perfectly.

Beyond universal needles, you might encounter specialized types like ballpoint (for knits) or denim needles. While universal needles work for woven fabrics, a ballpoint needle is better for stretchy materials. For a machine like the GX37, which is often a first machine, starting with a good universal set covers most everyday sewing needs.

Quality and Durability

A needle’s construction affects how long it stays sharp and how smoothly it glides through fabric. Look for needles with a polished eye and a hardened tip, as these resist bending and reduce friction. The SEWPASAM set, for example, uses a chemical deburring process and a tip hardness of 750-850HV, which indicates a durable, precision-made product.

Cheap needles can have burrs or rough edges that snag fabric and cause thread breakage. Investing in a quality set, even if it’s slightly more expensive, saves you from constant frustration and potential damage to your projects.

Storage and Organization

Keeping your needles organized and protected is essential for longevity. A good storage case not only prevents needles from getting lost or bent but also helps you quickly identify the right size. The SEWPASAM set includes labeled storage tubes with large, clear markings, making it easy to grab the correct needle without squinting.

If you’re a beginner, having a dedicated storage solution is especially helpful. You’ll learn to recognize sizes at a glance, and you won’t have to dig through a messy drawer. The Brother GX37’s included case is a bonus for the machine itself, but having a separate needle organizer keeps your workspace tidy.

Final Thoughts

For most sewists, the Brother GX37 37-Stitch Sewing Machine with its included universal needle pack is a fantastic starting point, giving you a taste of what works for everyday fabrics. However, to truly expand your creative range and handle everything from delicate silks to heavy denim, the Universal Sewing Machine Needles, Sizes: 65/9 set offers a comprehensive, well-organized solution that we highly recommend for any GX37 owner.

Frequently Asked Questions

What size needles does a Brother GX37 use?

The Brother GX37 uses standard HAx-1 needles, which are the most common type for home sewing machines. This means you can use a wide variety of universal needles, including the sizes 65/9 through 110/18, depending on your fabric.

How often should I change the needle on my Brother GX37?

As a rule of thumb, change your needle after every 8 to 10 hours of sewing or at the start of each new project. If you notice skipped stitches, fabric snags, or thread breakage, it’s a sign your needle is dull or damaged and should be replaced immediately.

Can I use denim needles in the Brother GX37?

Yes, you can use denim needles (size 100/16 or 110/18) in the GX37, as long as they are HAx-1 type. These heavier needles are designed to pierce thick fabrics without bending, making them ideal for jeans, canvas, and upholstery.

What is the best needle for quilting with the Brother GX37?

For quilting, a 75/11 or 90/14 universal needle works well for piecing and general quilting. If you’re quilting through multiple layers, consider a 90/14 or even a 100/16 to handle the thickness. For more tips, check out our beginner sewing machines guide.
