To all of you that are having trouble with your feather weights. Those FW were made so small that there is no room for error. If you guys don't put the bobbin casing in right, with the little arm in the notch or seat the bobbin correctly they will not sew. In order to get those machines so small - there is just no fudge room -- everything has to fit perfectly. If you get a thread caught in the bobbin casing, it really screws up the machine -- it won't sew. I'd get a really good book like "Featherweight 221 The Perfect Portable" by Nancy Johnson-Srebro. Really study the fit of the bobbin case, the throat plate, and how to insert the bobbin. Those are absolutely wonderful precision machines, but they have no room for errors. On a good note, it is almost impossible to ruin one, so most problems are human error!
