Why is my bobbin thread pulling through?

Why does my thread loop underneath?

A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.

Can I use embroidery thread in my bobbin?

Just buy a simple white bobbin thread designed for an embroidery machine either in pre wound bobbins or in a big spool and you are good to go!

Why is my sewing machine not stitching underneath?

How do you tighten thread tension?

Changing Bobbin Tension

You should see a small screw on the flat/closed side of the bobbin case. Turning the screw a tiny bit counterclockwise will loosen the bobbin tension; turning it clockwise will tighten the tension.

What weight is OESD bobbin thread?

This is a 60 weight thread which means it is very light weight. Because it is polyester, it is very strong. If you were to wind a full bobbin of this thread, it would go a long way. When I upgraded to my Bernina, it used a different type of bobbin thread from OESD.
