Although it might sound silly, using the correct type and size bobbin for your machine makes a huge difference in stitch performance and quality. There are many types and sizes out there, but the majority of bobbins that we see in the Studio are Class 15-A Style sized bobbin.

If you are unsure of the size of the bobbin in your machine, please visit this webpage onĀ Standard Bobbin Sizes and how to measure for them.
