I have the Brother EX660 and SQ9000 Top load bobbins. The EX660's bobbin case was $35 to $50 so I still don't have one for it.

I have one top loading machine but there is no way to adjust the tension on it that I know of, It doesn't have a case, just slots to run the thread through. I leave one slot or both empty for looser tension.

Thanks, BellaBoo, I've done the same thing, an extra bobbin case!

That's a really great idea.

guess I need to price them again.
One is the Elna Quilter's Dream, haven't priced it in 6 years or so.
The other I would be interested in a second bobbin case is the HQ16.

Thanks for the great tip. I'm always scared to change the bobbin tension. :shock:

If the bottom is bunching up I think it is the to tension you need to adjust.
