Imagine my surprise when there were a bunch of Class 15 bobbins included with the (old) Bernina 930 that I purchased!

These bobbins also fit my Singer 237 (a plain Jane machine from the early 1960's)

I just thought it was interesting.

I have not tried the Bernina bobbins from that machine on the Singer 237, though. Love that 237 - wish I could find a couple more of them!

I would be very careful in using another bobbin besides a Bernina. I bought my bobbins at JAF.

They are actually the same bobbins that came with both of my Berninas. They have little diamond engrave on the inside curve where the thread will wind around.

Yes, be careful, but it is great when you can use the same ones on machines that you use -- my ancient Singer and 78 Kenmore use the same metal bobbin, making it so convenient

So cool! My Pfaff Tiptronic and my Babylock Serenade use the same clear plastic bobbin. Love it, because I can use an already loaded bobbin of thread for either machine.

I have had a few minor problems and traced it to bobbins that were off brand. I ordered the machine Janome and can really see the difference even though the first were the right size they were a bit thicker.
