Frequently Asked Questions

What is an L-style bobbin and will it fit my machine?

L-style bobbins are commonly found in older domestic machines and modern multi-needle embroidery machines. However, most current home sewing, quilting, and embroidery machines from brands like Brother, Babylock, Janome, Elna, and Necchi use Class 15 bobbins as the industry standard. Always check your machine’s manual to confirm the correct bobbin size before purchasing.

What is the difference between Magna-Glide and Supra-Glide bobbins on this page?

The key difference is the core. Magna-Glide bobbins feature a magnetic core that provides a slight, consistent drag to prevent backlash and over-spin. Supra-Glide bobbins are a more economical option made with the same high-quality thread but without the magnetic core. Both are excellent choices for reducing lint and improving stitch quality.

Will these bobbins really improve my embroidery stitch quality?

Absolutely. Most embroidery issues, like puckering and “bird’s nests,” are caused by improper bobbin tension. Because Magna-Glide bobbins are wound by machine to a perfect, consistent tension, they establish a flawless foundation for your top thread, resulting in cleaner, flatter, and more professional-looking embroidery.

What size needle should I use with Magna-Glide bobbins?

Because Magna-Glide bobbin thread is a fine 60wt polyester, it pairs well with the standard needles you already use. For most embroidery and general sewing, a size 75/11 or 80/12 embroidery or universal needle is a perfect match.
