Hubby just called and he fixed the old bobbin case with sandpaper. What would I ever do without Hubby? I love sewing with well working machines. The achilles heel of my Elna is the bobbin case. I still would like to buy a supply of new bobbin cases. Also, we can't figure out how the bobbin case moved when the machine hasn't been moved and only light straight stitching has been done on it. Oh well! Look forward to hearing a discussion about this if it is a problem for others.
