Guess it pays to read the instructions. My BSR was acting up yesterday and I went to the Bernina web site to see if I could get some help. Two things - they say to set the needle position 2 points to the left (swear I never heard that before) and they caution use of chalk as a marking medium because it clouds up the lens. I had been using the "pounce" product and now that I'm off that and have moved the needle things are going really well!
