[quote=DogHouseMom] The only thing I have noticed about thread is that my Janome doesn't like different thread top and bottom. Other than that ... I need to pay more attention.
My Janomes - Gold and Platinum will take Bottom Line in the bobbin (I buy Superior Threads prewound) but not as the top thread. I use Aurifil 50wt or Masterpiece 50wt as top thread.
Whereas, my Bernina takes BL top and bobbin.
