Husqvarna Viking does not recommend the prewound bobbins for the #1+ (which I used to own) but they work in my Designer SE. I don't know why they work in some machines and not others.

I've also heard not to use the Sidewinder for bobbins used in Husqvarna Viking machines...again, never heard why.

So it must be only certain Singers?

I love my sidewinder!! For the cones and large quilting spools, I ordered a "DeelyBobber" adapter from Newark Dressmakers Supply. It lets you use the large spools on a small spindle This adapter is great for my machine too.

QBeth, I don't know how to copy and paste so I'll just respond to your post this way, I hope you don't mind. I have both the Viking D1 and Viking SE I have ALWAYS used pre-wound bobbins in them. Never been a problem for me, though when I bought my machines they told me not to use the pre-wound on the cardboard to use the plastic ones. I think they're the L pre-wounds.

You have to just try one on your machine. They told me not to use on mine and mom's brothers either but they work perfectly. I love the Glide bobbins they are great. Hoping they will work on my Viking mega quilter also.

I have a Singer Futura CE-150. It's a sewing/embroidery machine. The people that sold it to me, also sold me pre-wound bobbins. The bobbins weren't singer, or 15J. They fit in the machine and worked fine UNTIL about a month ago. During an embroidery project, my needle bent, the machine locked up, and started beeping very loudly. When I got the hoop loose, the bobbin case had popped up and broke the bobbin cover. I read everything I could in the manual and online. After many hours of that, I called Singer. They said using the pre-wound bobbins messes up the timing of the machine after a long period of time. I had to spend $30 in gas and $90 service fee to take it to closest Authorized Singer maintenance guy.(55 miles one way)
It's super frustrating!! In my opinion the pre-wound bobbins are sooo much easier, especially for embroidery. BUT, don't think I'm going to use them again.

A size L bobbin is not the same as a size 15J bobbin. That's why it won't work.

If you have a class 15 machine, you can use a class 15 prewound bobbin.

A class 15 is not the same as a 15J bobbin, so that would not work for your 15j machine, either.

Bobbin classes must match exactly. 'Close' is not good enough.

Viking says no because they wind the wrong way, however, one of the clerks said if you turn your bobbin upside down & wind they would be okay. The thread has to be wound left to right and I guess the side winder goes R to L? But one other thing the repair man told me the prewound bobbins can ruin your software in you machine that tells you when your bobbin runs out. The prewound would not work on my Viking Designer SE. When they were about to run out it pulled my stitch plate out, broke my needles and after the second one I did not use them anymore. I was so afraid I had damaged my machine, but thank goodness it didn't.

"Viking says no because they wind the wrong way, however, one of the clerks said if you turn your bobbin upside down & wind they would be okay. The thread has to be wound left to right and I guess the side winder goes R to L?"

With very few exceptions, Singer Touch and Sew being one of the few, bobbins are the same on the top and bottom. Therefore, it would not matter if the bobbins were wound clockwise or counter-so, because one must hold the bobbin so the the thread comes off to the left (or the right, depending on your machine), so the point of direction of the wind is moot.
