I just realized this is a terrible picture. But you can see the bobbins and that's all that matters. I need some Bobbin help!! The bobbin on the left is for my pre 1960 Singer Spartan. It's somewhat beveled or curved a bit. (Click on the picture for a much better view of bobbins.) The bobbin on the right is for my "newer" Brother machine. Although, I perfer the metal bobbins. Have any of you ever seen the bobbin on the left? Do you know where I can find some? I've never seen them before.Help! Please!
