Meant prewound sorry, predictive text on iPad!

Never used generic...always buy the brand name........not worth the risk of causing major ($) damage....

use their brands only.

I bought some (Dritz?) generic green plastic bobbins at Hancock that said they would work in my Viking. Seems like some of them do and some of them don't. When I have a problem my first correction is to put in a Viking bobbin. Usually does the trick. Worth the money to try. The Viking ones are ridiculously expensive! Come on, it's only little bits of plastic! I really dislike being stuck with an expensive name brand.

I have always used the green bobbins that came with my"Husky". Purchased more at a higher price than generic bobbins, but had no problems with the green ones. Don't think I will try the generic ones. That might be asking for trouble.

I have a D1 and a DIamond. I use the green ones, and there are also multi-colored ones available. But I do use pre-wound (both plastic and cardboard sided) almost all the time. Only use "colored" bobbins when I need to match bobbin thread. I bought a gross of white and black pre-wound and haven't had to buy more! I think the problem is when you are using bobbins that don't fit, but I haven't had an issue unless I try to use the clear ones for the little Janome, then they don't work!!

My Lily 540 has blue bobbins and if I use them in the Sapphire 870Q instead of the green ones, the thread low warning on the bobbin doesn't work.

I only use the clear with the H on them. I have an older viking and have not seen the green ones.

The machine I bought came with 11 and the dealer had a 20% all things Husqvarna/Pfaff so I stocked up on some. The multi colour packs (of 20) ended up being cheaper per bobbin than the green pack (of 10).
Not to include I got a few other things too. Merry Christmas to me!

Thanks for the advice , I think I'll stick to the official ones.

You have to use the ones made for the machine but they do have other colors besides green. You also can't wind them on a sidewinder because they wind in the wrong direction that the machine does. You can tell if you have them in right because the words stamped on them will be facing upwards.
