I am wondering if any one knows what machine would use these as I have alot of them, they have a plastic core in them, I did a quick seach but didn't find a match. They are about 1/2 and inch high, so too tall for my brother machine which also requires a bobbin holder maybe thats what I should ask... is there a machine that doesn't need a bobbin holder ???
The industrial sewing machines use these as well. I have a juki and use both pre-wound and regular in mine. Usually there is a number or letter on the bobbin itself or on the box, that will help to determine what you have and what it will fit. Hope that helps.
I don't have the box they may have been in or any numbers to go by.. thats why I am lost, but I'll search the long arm machines and so if they match. Thanks girls !!
