Dual Sew Sewing Machines - Recent Questions, Troubleshooting & Support
Why is the bobbin thread looping and catching on my sewing machine? The stitches are uneven, too.
Hi Sylvia,
Your problem is an un-matched tension of the threads. You mentioned doing an adjustment recently. That is the problem area.
If your bobbin thread develops loops on the top side of the fabric, you need to tighten the bobbin tension.
There is no easy method for this and you will have to do it slowly -
tighten, test, re-tighten, test.... until you get a near perfect stitch.
I haven't come across a portable device specifically designed to set thread tensions.
