unconditional acceptance - Sadie

hi
up front i am relatively new to this and getting help myself

what i have been told is that you should not need to adjust the bobbin tension--and to leave it alone, and adjust only the top tension. that said, there is a screw (tiny) on the side of the bobbin case--lefty loosey, righty tighty-- a little goes a long ways--same as any machine.

good luck

I was hoping to see more posting for you, as I don't kow a thing about a Joanome 200e. *4U

I have a Janome 350E. It sewed perfectly until I changed my brand of bobbin thread. I was told Janome machines only like Janome bobbin thread, but it is rather expensive compared to other brands. For the same price as a 1,000m cone of Janome I bought a 10,000m cone of Barnyarns own make. I experimented and found that by loosening the bobbin screw just half a turn (like Undecided descibes) every thing now works fine.

Good Luck, hope you can find an answer, I have a Baby LOck ESE2.
