What should I do with these prewound paper bobbins?
I got these in a box of sewing items at an auction last summer. I think they were in a box that said shoe machine but I must have put them in this tin. They say Summit Thread Co. style G on each paper bobbin. It's a very heavy waxy thread and I tried to look up some information and found an industrial thread supplier that said that style G bobbins are often for upholstery commercial machines. They measure 13/16" across, the hole is 3/16" across, and the depth is 3/8". There are 43 green, 36 red, and 4 partial red bobbins. So what do I do with these? I'm not going to have a commercial machine. I know some of you buy those. Is anyone interested in them?
