The guy I'm getting my singer from insists that only vintage round bobbins will work on my machine. I was googling online and found on ebay bobbins that are described to work on 66's and 99's. I own a sidewinder. Should I try these other bobbins or just go with the ones that are coming with the machine. He said he could give me 4 with the machine.
Do you guys think the ones on eBay are worth it?
