Sewing Machine Bobbins for Everyday Sewing

A sewing machine bobbin holds the lower thread that forms a stitch, working with the upper thread as the machine moves through the fabric. If the bobbin is the wrong size or doesn't sit correctly in the bobbin case, it can affect thread tension, feeding and the overall quality of the stitch.

Our range of sewing machine bobbins includes clear plastic and stainless steel options for standard domestic sewing machines. Plastic sewing bobbins are lightweight and transparent, making it easy to see the thread colour and how much thread remains. In contrast, metal sewing machine bobbins offer a durable alternative designed for repeated use.

The right bobbin depends on your sewing machine and the type of bobbin it is designed to take. Our bobbins are available in 15K and 66K sizes, with pack options including single bobbins, packs of five and packs of 20. Compatibility is another factor to consider and depends on your machine’s bobbin system, as sizes and loading styles can vary between models. 

Our metal sewing machine bobbins suit many standard front- and top-loading machines, including models from Brother, Singer, Janome and Baby Lock. The plastic bobbins are also compatible with Elna machines, so check the manual before choosing.

For regular sewing, quilting, embroidery and garment projects, having correctly sized sewing machine bobbins ready can make changing thread colours and continuing a project much easier. The reusable design can also be wound with fresh thread as needed, giving you a practical way to keep spare bobbin spools ready for different projects.

If you’re unsure which sewing machine bobbin is suitable for your machine, we can check it for you and help you explore your options.

Frequently Asked Questions About Sewing Machine Bobbins 

What Does a Sewing Machine Bobbin Do?

A sewing machine bobbin holds the lower thread that works with the upper thread to create a stitch. It sits inside the machine’s bobbin case and feeds thread as you sew.

What Is the Difference Between Plastic and Metal Sewing Machine Spools or Bobbins?

Plastic bobbins are lightweight and transparent, so you can see the thread inside, while metal sewing machine bobbins or spools are made from stainless steel and offer a durable option for repeated use. The important aspect is whether the bobbin is the correct size and type for your sewing machine.

How Do I Know Which Sewing Machine Bobbin I Need?

Check your sewing machine’s manual or the existing bobbin for the correct size and type before buying a replacement. Our bobbins are available in 15K and 66K sizes and we always recommend checking your machine’s requirements for compatibility.

Are Sewing Machine Bobbins Reusable?

Yes, reusable sewing machine bobbins can be wound with thread again when empty, as long as they remain in good condition and are suitable for your machine. The metal and plastic bobbins in our range are designed for repeated use.
