This link is to machine models and bobbin type.

I had to check my manual to get the correct size for my machine I recently bought some too, still waiting for the order

As far as I know most of the newer H/V machines take the L sized pre wound bobbins.
My Designer 1 takes L size.

thanks for the link thisis very helpful....soozie...sorry in the wrong place should be under capoodle

Here is a better list.

This is where I found my information for my HVDesignerII......

I noticed you have a Husqvarna machine, I have a Ruby. My dealer tells me never to use prewound bobbins, is that what you are looking for and have any other cuties been told never to use prewound in their machines, just wondering because my dealer was really insistant on this point.
Thank

Hi DeVon, I cannot answer your question but I have recently changed to prewound for my old Bernina. I am absolutely thrilled with the result. I realise that with the prewound they are tightly wound - much more than I can do myself. I have always had trouble when doing fonts with the bobbin thread coming to the surface. With prewound there is no trouble at all.

When Husqvarna/Viking came out with the Designer 1 machine they then starter to recommend using Nebs L sized pre wound bobbins.
Every newer model of machine that has a top load bobbin that they put out since the D1 should be able to use the L Sized pre wound bobbins.

I use Nebs and other name brand L sized bobbins in my Designer 1 with out a problem.

The only thing to watch for is that some have more thread on them than others do.
If they have more than 131 yards of thread on them you may have to pull a bit of thread off them so they turn easily in the bobbin case.

I am always amazed at the difference in info provided to consumers from dealers! I own a Viking Diamond (tol when I got it) and have always used prewound L bobbins. Never asked the dealer, just ordered them. I have gone through 3 orders of 100 each, and just recently my machine had to have a new transformer. It was covered under warranty and dealer (in new area, not the one I purchased from) never asked me what kind of needle, bobbin, thread I used...just fixed it at no charge! Machine is now 6 years old! Go for the prewound, easy peasy to use, toss the used empty case (can't be rewound on the Viking..you can use a bobbin winder but it can be too much thread or too tight) and go on and enjoy your hobby!
