preparing to make HSTs for star points July 2021 Last week, I showed you the stars made with bonus HSTs . Since I needed more stars, I used the eight at a time method to make more HSTs for star points. A week ago, I took my sewing machine to the Bernina dealer in Fort Collins, CO where it was serviced in May. Luckily, three technicians were in the shop, and simply by hearing the machine run at high speed, one of techs was able to diagnose the problem. She did some adjustments, and the machine ran smoothly without any problem. I was not charged for the adjustments, and it's been running great. I always oil the machine (usually after five bobbin changes), but the technicians agreed that machines should be oiled after four hours of sewing.
