First, while I don't know anything about the Futura; however, I would like to relate a conversation I heard in a Hancocks store 20 years ago.....The two women had the same machine. One couldn't get the bobbin to wind. The other woman asked if she wound the bobbin slowly....she said, "Yes," the other woman indicated that was her problem....wind the bobbin fast. I have never forgotten that, and have wound my bobbins (at least on takeoff) fast ever since... (Actually, just on takeoff!!!) Maybe that is the difficulty you are having???
