I use both for my Brothers and used both for my Singer. I never had any problems with either one.

Absolutely! I wonder if some of the ppl who complain about 'unfixable' tension issues when FMQing on a Janome are using cheap bobbins? Why would you spend a small fortune on a machine then skimp a few pounds (or dollars!) buying cheap bobbins? Makes no sense to me! :?

As a newbie I was interested to read this. I have only used the bobbins that came with my machine at the moment but I will be careful when I buy some more. Thanks for the advice.

I use metal in all my really old heavy machines and I use plastic for all my newer plastic machines.

I wasn't paying attention and bought Singer bobbins that are within millimeters of the bobbins for my machine. But the slight difference in size and the rounded versus flat bobbins make a huge difference - massive nests with the wrong bobbin.

When I went looking for bobbins for my Bernina, I was very careful to get the correct ones.

Cheers, K

Brother bobbins are the same way. the size my ULT takes is SA 155 (3/8 inch). my DD's machine-a small, lightweight Brother takes a different size, SA156(1/2 inch).

Same here. And yes, bobbins do make a difference. I've found that out through painful experience.
Now I use plastic Janome bobbins for my two Janomes, and I use metal Singer bobbins for my old Kenmore which was made by Singer. All of my machines have happy smiles on their sweet faces.

Donna Mae - totally off of your subject, but your name brought back instant wonderful memories. My mother's name was Dona Mae and has been gone for 30+ years. Thanks for a quick memory of love. If you have a Janome - my guy says definitely use the plastic ones because the metal ones will ruin your machine.

my guy told me that if the bobbin will be sitting in a plastic "seat"
(bobbin case or bobbin chase) it should be plastic regardless of whether it's a drop-in or not. and vice versa for metal. they should always match up. it makes a huge difference in tension.

I only use the bobbins made for my Bernina which are metal.
