Has anyone tried to use these in their vintage machines? I got a box of 100 for $5 and they fit my other machines that take a 15 bobbin. Will they work in my 15-91 without messing things up? I'm making a charity quilt and will be using the 15-91 to quilt it with. If they'll work it sure will save time and my working thread since there's a lot more on these.

Are they those cardboard ones? I imagine if they work on a 15 clone, they'll probably work on a 15-91

These are plastic bobbins and work great in the Singer Merritt and my Necchi.

I see. Plastic bobbins don't work well in my machines but they do in my daughter's 498K. Maybe you'll only find out by trying one.

Jenny at Sew Classic now recommends plastic 15 class bobbins for all 15 class machines. If they're the 15J bobbins they may not work well. If they're a little sloppy in the bobbin case you can always use a bobbin washer.

I've never had any the correct size to try. I bought some 15L prewound bobbins which don't fit in a 15. I used the paper bobbin for the top thread and wound some onto metal bobbins for the bottom thread. It was worth the bit of trouble since the thread was a bargain.

I have some pre-wound bobbins and they do work in all my class 15 machines. But the thread is really huge so I haven't found a need for it.

As for the plastic bobbins, I've had no trouble with them in any machine as long as I use the correct class bobbin for the machine.

I've also bought both the metal and plastic class 15 bobbins from Sew-Classic and fail to see why she doesn't recommend the metal ones. They've been very good and have worked in my machines.

Joe I thought someone on here mentioned QC problems with her supplier for the metal ones. I was under the impression she was discontinuing her metal ones for that reason.
You can use plastic bobbins in machines designed for metal ones with no problems. Some newer machines are designed for plastic bobbins. Use ONLY plastic bobbins in those.

I guess I don't sew enough for it to be a huge issue for me to wind my own bobbins. It only takes a few seconds and if you have more thread around there's no reason to unthread the top spool. I find myself switching colors a lot and if I wound them in advance they would be the wrong color anyway, though for bobbin thread it's usually not critical.
I can see the advantage to prewound bobbins if you're production sewing but that's about it.

Machine embroiderers are big users of pre wounds. My BFF buys hers by the box. Being the frugal(read-cheap) person that I am, I bought a big cone of bobbin thread and wind my own, at least a dozen at a time. I do the same before starting any sewing or quilting project. Part of my prep work is winding bobbins so I don't run out in the middle of the project.

I know several people that use them with their Baileys - and they take a regular size class 15 bobbin. Several say they have to strip off a few yards of thread, then they work just fine. I've never tried them - go ahead and try them, you aren't going to hurt the machine, and they'll work or they won't.

When I am working on a quilt, I normally wind 10 bobbins before I start - though I do so with my silver 15-91, as I can get a much tighter, even wound bobbin that way. I do use my fingers to guide and apply more tension as I'm winding.
