Roberta---Well,  that is not very encouraging. I was thinking I would replace all my generic, pre-wound bobbins out for only Janome branded ones and wind them a bit slower and it would probably improve this issue. But your experience says different.Still, after closely examining a bunch of the generic pre-wounds I have in my possession, I have decided to order some Janome "J" bobbins and a cone of 40 wt bobbin thread. For a start.  The rest of my decision will be coming after I have been stitching for a while with the Janome bobbins and not pre-wound.  There ore so many variables with embroidery!!!
