I may have to take a screwdriver to the bobbin case tension, but before I do that, I'd be grateful for any comments or advice that anyone can offer. I should add that I really don't think these problems are my incompetence - or not just that, anyway - as I've produced perfectly adequate FMQ on other machines.
I was using a top stitch needle and Janome embroidery thread top and bottom.
