What she said ^^^^^^^^^^^^^^^^

I recently cleaned my Bernina 180 before a class and put in a new needle. I did a test sew and kept getting occasional little loops on the back. Rethreaded, took the bobbin out and put it back in. Still had occasional loops. As the machine was sewing fine before the cleaning and new needle, I put another new needle in. Sewed fine. I took the class and had no problems. You just never know.
