Husqvarna bobbins
I have a question regarding Husqvarna bobbins - the ones for a Ruby - are you restricted to using their name brand ones or is there a generic version that will fit? I know my Janome and my Elna use regular class 15s but the Husqvarna and Pfaff machines have a type embossed with their name and can only be put in one way. This apparently prevents one from inserting the bobbin incorrectly.
Thoughts???
TIA
