Hi Kate,
My Kenmore doesn't have a classic bobbin holder. The bobbin drops down into the machine from the top. I could probably adjust that--although there are no directions, I've found the screw--but the machine sews straight stitches so well, I'm loathe to change it.
I'm thinking I may need to put off FMQ (no, not the friendly monkey quilts; the free motion quilting) until I can upgrade. However, after feeling as though I ought to take the quilt I was working on and cut into little pieces, I'm not a fan of machine quilting at all at this point. Yes, there's a story to this, which I will post.
Best regards, Michelle in Nevada, USA
