How do you control whether the bobbin is tightly wound or looser? Doesn't the machine control that?
On my machine there are two thingys that the thread wraps around before it is wound on the bobbin. When using the mono. thread I only use one those guides and use the half speed on the machine. When I first filled a bobbin with mono., I did it the same way as with cotton and it was so tight that I couldn't get the bobbin off the spindle thing and had to break it off. I think its because the mono. stretches while filling .
