It is different .I have trouble with bobbins My machine never will wind a bobbin right and the thread breaks often.
I just lack bobbins for my emb mach. I am down to 3 now after moving. I sit at my mach when it winds bobbins and I help guide the thread evenly on the bobbins
hi lenamae try winding bobins at a much slower speed i think this will help you.good luck cathy
